I don't have a problem with that. I don't think it should really matter, but I'm a pragmatist and realize that it really does matter.
However, I seriously doubt that if all the Flamboyant Gays were to tone it down and live "normal" lives (whatever that really is), people would feel better about gay marriage. I think the bigotry would still be there, only they would have even less of an actual argument. IMO, the argument as it stands now is about as thin as tissue paper, but then they would have to fall back solely upon the original arguments which clearly show bigotry.
