Being gay is a fetish.

[Esquilax]

Well, up until the point where he said "I am going to be straight now." You know, like no person has ever done, ever.

I'd be surprised by the fact that homophobes don't see the flaws in their arguments, but it's all a part of being human. They don't see why nobody would choose to be/remain homosexual when faced with discrimination ranging from simple disgust to death threats.
If I could've chosen to be heterosexual, I would have. In fact, I tried to. Then I admitted to myself I wasn't.

They have the perfect pre-packaged non-answer to that: we just love our sin too much to make the obvious choice.

'Course, then we get into justifying the existence of sin, which they never seem to do, leaving the argument right back in specious territory...
