    That depends on who you talk to. Orthodox and (to a lesser extent) conservative Jews follow the "law of matrilineal descent", which means you can only be considered Jewish if your mother is considered Jewish. That's not entirely true for conservative Jews, but it's close. So there *is* a strong common heritage for Orthodox and conservative Jews, if you trace things back far enough. http://judaism.about.com/od/whoisajew/a/amijewish. htm

    And of course, Judaism was originally centered on the Hebrew people, so I think you'll find a strong correlation between people who follow Judaism and people who have Hebrew heritage.

    With all that said though, you're correct that I probably should have said "Israeli", since that was how the topic started; however, the post I was replying to said "Jews and Arabs", so I was merely continuing the mistake.

    As for the difference between Jews and Arabs, there aren't many. As in none, genetically you can't tell them apart.

    Can you back that up?

    A peer poster mentioned this but didn't really put much force into it: if you remove the restriction of looking at a single gene only, then it becomes much easier to commit bio-genocide.

    You need to sort them out based on a rather non-existent grouping... that is something only racists can do, not viruses. [...] There are certain genes which exist in varied frequency but none that are that isolated.

    Imagine 80% of the population of a particular "non-existent grouping" has a particular gene, while 20% of the population outside of that population has the gene (I think that's being generous -- much more effectively discriminating genes could likely be found). Now imagine there are 10 of those. It would not be hard to believe that 1 in 3 of that "non-existent grouping" has at least 3 of the genes (assuming the "non-existent grouping" is not based purely on appearance, but also evidence of ancestry that ties the group together), while less than 1% of people outside the group has 3 or more of the genes. This is assuming the genes have independent distributions when considered either within the group or outside it; this would almost positively not be the case, but I'll assume that it probably doesn't hurt my case too much (though it may in the Jews/Arabs example, I admit).

    So, can 10 genes like that be found, and can the virus be made to kill someone with several particular genes? If you could make a virus that targets the combination of 3 particular genes (again, assuming the genes have independent distribution within the group), then one virus like that could kill off a third of your group, while killing less than 1% of people outside the group. Make a second virus with a different 3, you kill off ~1% of the remaining outside population while killing of a third of what remains of the group. Do that with 2 more viruses and you've cut the group down to less than 20% of its original size, at the cost of 4% of the outside population.

    Does anything in that scenario sound so implausible? Do those sound like numbers a hard-core racist would go for?

    I think you, as most people, miss the biggest part of the that expression. It is not supposed to be an insult to teachers. It is saying that in order to teach someone else how to do something, you have to understand the difficulties in doing it. Could Mozart have taught someone how to play the piano? Perhaps, but if the student isn't a musical genius, I bet someone who had to struggle to learn to play would have an easier time teaching them. When something comes naturally to you, how do you understand what is going on when someone else is struggling to pick up the basics? Even if you can figure out how to communicate it to them, how do you know what sort of practice to recommend, if you never had to do it yourself? For an example many slashdotters can probably relate to, take someone with a natural talent for math -- how easily is someone who never needed a quarter the explanation given by most teachers going to sit down and go step-by-step through the reasoning with the one student who needs twice as much explanation as the rest of the class?

    Maybe if teachers were offered a better salary, there would be more competition for the jobs. As it is, many very capable people avoid teaching because it's common knowledge that it pays crap. And maybe if teaching didn't involve working mostly with students who are motivated only to get a certain grade (as opposed to learning and exploring new ideas), it would be a more desirable job to have, regardless of salary. As someone who got through grad school working as a TA, I can tell you from experience that it is very discouraging to be faced with students who don't care what they learn, and don't even care if the class could be interesting, as long as they get their required credit without hurting their GPA too much. When 95% of the class has that attitude, it's very hard to stay motivated and productive as a teacher.

    Or, taking the other responder's idea a little further, set it at some higher amount than $50k (maybe $100k) but instead of taxing 100% past that, you tax at 80% and prohibit tax credits or deductions from reducing your tax liability below 80% of your post $100k income? In other words, you add a new, fairly simple tax rule that tells you to calculate your income + social security + whatever taxes as you do now, and also calculate 80% of your income minus $100k. Your tax liability is the larger number.

    Think $100k is too low? Fine, make it $500k. Both the percent and the starting point could be tweaked so that there is still some incentive to work more if you want to earn more, but overall yes we discourage people from making tons of money. You will be hard-pressed to convince me anyone "needs" to make more than $500k a year, and I do think that sort of thing should be deterred. Taxing it at 80% would have the twin advantages of deterring ridiculous incomes to a large extent and increasing government income where it's not deterred.

    Just in case you are wondering, I think that such high incomes should be deterred for multiple reasons, but one of which is the opportunity benefit -- anyone or any company deterred from giving $2M of income to someone since they would only make $380k off it (using the $100k/80% rule) is still going to have that money to spend. Maybe they only give $1M to the person, and then $100k to 10 other people. Voila, we're not just cutting down the largest incomes, we're also encouraging many lower incomes to increase.

It's like the difference between winning a game by playing well versus winning game because, mediocre though you played, the other team made repeated mistakes. With only two parties, a loss for the Republicans usually means a win for the Democrats, but looking at the political situation and recent news and events with a little common sense can tell you whether the Republicans lost because they were unpopular or the Democrats won because they built popularity.

    With a small homogenous population that has a decent work ethic, socialism works fine. The problem is that there are immigrants who don't share the same values

    It's not that those populations inherently have a decent work ethic and are thus able to make socialism work, nor does it have anything to do with the size or homogeneity of the population. It's just that societies without a system that stifles a sense of internal motivation produce people with a decent work ethic by default. On the other hand, immigrants who grew up with capitalism have learned to need outside motivation to be productive (read the link above) -- as you essentially state, they're the ones who lack the decent work ethic, not the ones native to socialism.

    In other words, the problem is not that socialism doesn't give much outside motivation -- the problem is that capitalists tend to be lazy without outside motivation.

Then parent has to go on a business trip for a couple days, and asks a friend to watch the child, but forgets to mention the candy-homework deal. The first day, the child tests the boundaries, and asks for some candy; the friend gives the candy. So, the child doesn't do their homework, and merely pretends to work on it.

    Sounds like you didn't do the math. ;) Given the choice, if you could save 300,000+ soldiers by dropping two bombs, would you do it?

    Not if I could do it by dropping one bomb, especially if I thought I could always drop the second later if it proved necessary.

    Let me point out that in my previous comment, I never questioned whether dropping nukes was better than an invasion of Japan. I did the math, and I never questioned it -- there is no need to debate that point with me. I questioned whether dropping two nukes is justifiable compared to the option of dropping one.

    You and another poster gave some good reasons for dropping two. However, I must say I am not yet convinced that one nuke could not have done the job, or more accurately that one nuke would have been so significantly less likely to succeed (as you did convince me that it would have been less likely to at least some extent) that dropping two was clearly justified. I do understand cost-benefit analysis (I say this because you seem to assume I don't). You and the other poster have given some justification for dropping two, but not enough to convince me that the difference in benefit between destroying one city and destroying two cities was worth the difference in cost between destroying one city and destroying two cities. Besides, would it not have been possible to drop one, and then drop the second if they did not surrender within a certain timeframe? Yes, I'm sure it would have been much harder to get the second nuke through, and maybe required the sacrifice of several escort planes, but (if we could have done it and if it would have worked to force a surrender) that hardly balances out against the possibility of only having to destroy one city instead of two.

    Maybe you can convince me that the reduction in probability of getting a surrender from only one nuke would have been so great that it was not worth consideration. Maybe you can also convince me that the second attack could not have gotten through if we waited for their response before dropping the second. But, if it is reasonable to assume that one nuke would have worked, or that we could have dropped the second one later and that that would have worked to get a surrender, then I think the loss of a few escort planes (or for that matter, even the lost of 10, 15, or hell even 20 escorts if necessary) do not balance out against the destruction of an additional city. That's what I meant what I asked "So the end justifies *any* means?" -- we avoided invasion, and that's good, but could we have done so with less cost of Japanese lives (i.e. could we have done so by destroying only one city)?

    Furthermore, the first point I brought up in my previous comment was intended to question the validity of the "ends" that supposedly justify the "means" dropping of both nukes. Specifically, you said (and even stressed) that part of the point was so we could achieve unconditional surrender. I questioned whether unconditional surrender was a necessary end, and you seem to have conceded that it was not. So, with that in mind, we can re-evaluate all the questions I asked above. Even if one nuke would not have been enough to get unconditional surrender, isn't it possible it would it have been enough for us to get an acceptable conditional surrender? There is historical evidence which suggests that the Japanese might have been willing to surrender even before we dropped the nukes if we had conceded as conditions of their surrender that we would have allowed them to keep their emperor and that we would not have tried him as a war criminal. (Furthermore, there is evidence the US knew this.) Even if this turned out not to be true, I think consideration of conditional surrender would have greatly increased the probability that a single nuke would have sufficed. At the very least we could have made those concessions part of our original offer, rather than demanding an uncondi
