I think there are two different issues here. One is simply do people have the right to set limits on who they want to fuck? Absolutely. It's their bodies, man. If someone does not want to fuck a guy who swings both ways, fine. If someone does not want to fuck a black man, a jew, an arab, an american..a midget without legs..an elephant...fine. It's not like they're denying people the right to vote.

On the other hand, people have to accept responsiblity for their actions, and clearly, prejudice towards bisexual and gay men is a fact in the adult entertainment industry. It is clear from the conversation in the Christian XXX link, and it is clear from Wayne's own comments about bi men:

Taken from AdultFYI: "I love men who are men," said Wane. "I don't fucking care how grizzly they are, sweaty they are. I don't care as long as they're real fucking men. I want men to be men. All the way. But the minute I found out he sucks tranny dick, that's it. I can't even look at the guy because that's all I think about. I can't look at him as a sexual human being any more because I know he has sex with men."

I am guessing that Wayne isn't the only one in the industry who does not view bi/gay men as men. As annoying as he might sound, kate is right.
