You're right. Each person will guess correctly 50% of the time. BUT, look at this table. The first letter represents the player's hat - (R)ed or (B)lue, the second the player's guess- (R)ed, (B)lue, or (P)ass, and the third the result -(T)rue, (F)alse, or nothing (X).
As you can see, each player guesses wrong twice and guesses right twice. 50%, as expected. But the group wins every time except for the first and last, 75%.

Can both sides at least agree to call each other by their chosen names, "pro-life" and "pro-choice"?
The problem is, calling individuals who solicit murder "pro-life" sounds like a bad joke.
I'm ok with "pro-life" as a label for the movement as a whole, but in this particular case it's painfully inappropriate.
