Paradox or hypocrisy?

I've run across several profiles (of presumably gay men) on various websites lately with things that bother me.

I've seen some that attack people for stating preferences in their profile ("If you won't date black men, then you're racist and should deal with that") and some that make me believe that the writer has been attacked for stating a preference("I'm vanilla when it comes to sex - don't tell me that I need to explore more").

I really don't get it. Most gay men have decided/realized that they prefer sex with men over sex with women [for the sake of this argument, it doesn't matter whether it was a "choice" or "genetic" or whatever]. And, I think that many would be upset if some straight person said to them "you're just being closed-minded, you should try sex with a woman". But, apparently some gay men feel that it's OK to tell other gay men what they should find physically attractive or sexually exciting.

Is there really something qualitatively different between "being attracted to men vs. women" and "being attracted to some race/style of sex"? Or, are these guys who are attacking other's preferences being hypocrites, or just not thinking?

Sometimes an apparent paradox just denotes that we don't have all the information. Sometimes, though, it just shows up hypocrisy.

Water kills

Apparently a study in today's New England Journal of Medicine (as reported on KCBS radio) found that drinking too much water can cause serious problems -- even death in athletes.

The thing to do is to regularly weigh yourself before and after training sessions, and if you weigh more after the session, then you're drinking too much water & should cut down next time. Do this regularly and figure out how much water your body needs.

As one of the people being interviewed on the radio said: Nobody has ever died of dehydration in an endurance event, but people have died of over-hydration.
