Ummm... because you are haters? And you're hurting the GOP at the same time. And as much as I don't like Republicans I like Demonkrats even less. So stop screwing around.
There are 50,000 pressing issues more important that whether or not a gay man gets arrested for something he does in his own house.
They aren't going to covert you. (Well, you Fundie types I'm not so sure about - that repression has got to be coming from somewhere) - They ain't going to convert ME at least, so I intend to leave them alone until they bother me.
(Islam, China, Bureaucracy, Excess Taxation, Gun Control, Education Freedom. Solve those and then worry about what gays are doing.)
