Why should Gays be Democrats?

I don't understand why gays are liberals. Really. OK, I get it. The 'pubs "hate us" and there's all this fantasy fear of fundamental christians (despite evidence that deep down every 'pub wants his thing worked, but we won't go there...) I suspect it has a lot to do with "If you hate me (i.e. don't invite me to your party), then I'll hate you back. Worse!"
Why do I say this?
Because liberalism isn't a natural fit with gay culture. (I won't speak for lesbians, they probably are "naturally liberal.") Gay culture is elitist, hedonic, and Ayn Randianly selfish. I don't see a lot of "connection" between "helping" the minorities, the poor, or making a larger government and the gay agenda. Well, maybe the underemployed might like unions, minimum wage laws and the idea if the government was bigger there would be more "jobs" in bureaucracy and what not, but still... a bigger government will be more intrusive (albeit "helping") and want more of your (affluent!) money to throw at programs that largely don't work.
And the military. OK, you can still get kicked out for being gay but has that changed since Sparta? Not really. If you're quiet a bit, what a bonanza! And enemies? My god, if you want to hate someone why not hate the people who want to KILL YOU (hint, they're NOT fundamentalist christians!) Gays being against military actions make no sense. We will be the first to "go" when "they" take over. See what's happening in Europe? Hel-l0? Does anyone care? JeeZus.
True the 'dems have always courted the gay vote, claiming their "big tent" is more inclusive, tolerant, blah-blah. But they also court black people and look where it's gotten them. Bad schools, dependency, poor leadership, lack of ideas generally, putting down anyone who's "made it" as white. Great.
I understand why gays HATE republicans, Bush, the military, christians, etc. but is that an excuse for BEING STUPID?
I think not.
I think there should be all-gay combat forces. I'm signing up!
