I think gay people tend toward the fringe segments of culture because the traditional mainstream culture rejects them. In other words, the gay community tends to skew toward the far left liberal edge because it's a beachhead of acceptance.
You tend to not see many gay Republicans. I'm not saying they don't exist, but that they're a minority even among a minority. You'll find some Jewish neo-Nazis too, or black Klansmen, or whatever. But they're not emblematic of their group.
Part of the problem with mainstream integration of minority culture is that the minority culture tends to separate themselves from any mainstream activity. There was a psychological study back in the '70s where they asked people of various genders, races, and sexual alignments (I never liked the term "sexual preference" as if someone chose it arbitrarily) and asked them to look in a mirror and tell the researcher what they saw, in the most general sense.
The white males tended to say that they saw "a person" or maybe "a man" whereas people of minority cultures tended to say that they saw "a ______ man" (black, gay, hispanic, Mormon, etc.) or woman.
What were we talking about? Oh, I don't expect the revelation of Pat's sexuality to change much. I mean, surely he must know he's gay, or even if he doesn't see himself as gay, must've wondered at some point why he was attracted to other male cats.
