    Just because they both deal with "space" doesn't mean that they're optimizing toward the same thing.

    Perhaps. Then again, perhaps equating breaches of privacy with Nazism may demean Nazism. Privacy is far from a universally agreed subject. There's significant movements to relinquish privacy, and they're not coming from despotic potential leaders, waiting for their chance to perform a coup on democracy. Equating Nazism this way may garner support for privacy, it also makes the word very cliché, especially for those who don't particularly care about the majority of their privacy.

    Please explain how is being forced to wear the Star of David on your breast because you are an evil judish sub-human hell-bent on destroying the master race fundamentally different from being forced to give DNA samples because you are an evil future criminal sub-human hell-bent on destroying the decent people ? Because I sure am troubled by the parallels I see, and would like reassurance that it's just my paranoia acting up.

    Holding the good of the state over everything, especially individuals rights and freedoms, is what Nazism is all about.

    If that's all they were about, then all my parents friends and family would probably be alive now, I'd probably be speaking German, and I probably wouldn't be so angry at the Nazis.

    You forget one important detail: sanity. Nazis that they were doing their nation (their "Aryan" race, to be exact) an important service by persecuting the judes. In their fantasy world, the judes were the source of all evil, so they had to be exterminated. In the Nazis minds, your parent's friends and family died for the greater good of Germany. They thought that Germany would be better off without them, and because the good of the state justified anything... the solution was as obvious as it was final.

    Of course their consciences acted up. Anyone's would, at the murder of millions of helpless people. But they heroically suppressed them and pressed on, doing what had to be done - or that's the way they saw it, anyway. It's pretty fascinating, actually, reading some of the messages exchanged between the members of Nazi leadership at that time. An insight into the level of self-deception human beings are capable of.

    Hitler drove Nazism to more than just the typical totalitarian regime.

    No, he didn't, and that's a very important thing to understand. Nazis were no worse than an average totalitarian regime, and Hitler was no worse than an average maniacal dictator. All totalitarian regimes leave a body count in the thousands, if not millions behind them. The only thing setting Hitler apart from an average petty tyrant is that he was the head of a very powerful European country, rather than a third world hellhole. Consequently, he could pillage and murder on the global scale, rather than being limited to inside his own borders; but that is a difference in the power, not the nature, of the beast.

    Besides, what these police are trying to do is far from totalitarianism (which implies an extreme), let alone Nazism.

    It is, however, a step to that direction. Totalitarianism creeps upon you. And frankly, the whole concept of taking DNA samples from children because you think they might become criminals later is quite hard to justify from any perspective except the totalitarian: state uber alles.

    Not that that's very surprising, since you didn't actually go through it, your parents did. So you wouldn't actually know it. But don't worry, the way things are going I'm pretty certain there's going to be a major war in Europe in my lifetime; the generation which actually experienced the last one is dying out, so the new one is once again free to engage in nationalistic bullshit and blow themselves to Hell for the sake of glory. Which might be prevented or at least postponed if people realized that this same shit went through before WWII. Pointing out the similarities with recent developments and Nazi Germany might help with that.

    They aren't references to Nazism. They are references to certain minor aspects of Nazism. To say they are references to Nazism implies a certain similarity between Nazism and the ideology behind this proposition, that the proposition and Nazism share some key values, which they mostly don't.

    Nazism is, at its core, a stereotypical totalitarian ideology. Surveillance and control are its core; saying that they're "minor aspects" is the same as saying that your heart is a minor part of yourself. The specifics of Nazi psychosis simply don't matter, except as to decide who, precisely speaking, they're going to blame for everything and mass murder; but that they were going to do that to someone is independent of them.

    Holding the good of the state over everything, especially individuals rights and freedoms, is what Nazism is all about. That is also what continuously giving new powers to the police is all about. The comparison is perfectly justified.

    It seems that Nazi is just a word that people wave around to make their cause sound scary, and consequently, it starts to lose meaning.

    "Nazi" is on its way of becoming a synonym for "totalitarian", since it gives such a good example of what totalitarian actually means and what it results in. It drives the point home better than mere "totalitarian" or "authoritarian" would.

    Soviet Russia did collapse by itself, but took nearly a century to do so, and even then the immediate reason for the collapse was that Gorbachev loosened the oppression and censorship. Power was not taken from him, he gave up some of it voluntarily - too much, as it turned out, resulting in an attempted coup and collapse. Furthermore, is Putin's Russia truly that much different from the old Soviet one ? Political murders (of Anna Politkovskaya and Alexander Litvinenko, to name two), Putin Youth, etc...

    The human immune system is astoundingly adaptable. The reason why you hear about the immune system failing (AIDs, etc.) is because all the OTHER hundreds upon hundreds (if not thousands) of possible invaders are crushed - either before we know or after a brief cold. AIDs, Prion Diseases, etc. are the very small minority.

    No. The thousands upon thousands of invaders who get crushed are familiar to the immune system. Every time there's a new one, or even sufficiently mutated old one, we have a major epidemic with a huge death toll.

    The only pathogens the human immune system can deal with efficiently are those it has been primed through natural selection to specifically fight.

    X and the graphical system in general is clearly the weakest point of modern-day Linux. It is an userland program, yet it has the same stability requirement than a kernel, and fails to live up to them. This is on top of various annoyances, like being apparently unable to switch the bit depth of the screen at runtime (affects at least Wine) and having to play around with modelines in config files to set up display modes.
