What I wonder is this: Why is it so wrong for people to be made uncomfortable by the idea? Of course it's not 'rational'. Why does it have to be? Why must every single person on earth happily accept everything? Naturally, being bisexual myself, I'd rather people weren't made uncomfortable by it, but there it is. People are made uncomfortable, males especially. Mostly due to cultural training, and possibly because of the fact that men are biologically wired to be quite a bit more sexually agressive than women are, and there's no changing that. So, by extension, the assumption is made that the average gay man is - mentally at least - drooling over random male bodies. Which, in turn, just makes some guys' skin shiver in revulsion. Hurtful as that is, it's a fact; men shouldn't be made to feel like they're evil for feeling that way.
The only way I'd get upset is if someone tried to revoke a gay man's right to take a shower in the locker room. Which, I noticed, isn't going to happen in the NBA. Besides, how many gay people walk around with a giant honking neon sign announcing their sexual orientation? Not many. I sometimes think we Americans make too large of a deal out of sex. If it doesn't affect the everyday functioning of the team or whatever, why bother even putting that flag out there for others to attack?
And, well..discomfort with homosexuality does not always make one homophobic. I am uncomfortable with plastic surgury, vaccinations, and crowds. Am I then automatically phobic? Nope. After all, I ride the train, administer vaccines, fluids, blood draws, and whatnot, and will likely have to have a form of plastic surgery to have a reasonably male-appearing chest.
