Why do straights hate gays? - Los Angeles Times
Kramer is absolutely correct that heterosexism is the last remaining bigotry that's acceptable to express in public in the US, and the only one with no legal recourse whatever in most jurisdictions. (I say "in public" in full awareness of what I finally, a little tipsy, confronted someone with a few weeks back: it's amazing the things people will say when they assume you're white.)
But even more sadly, at this time in history, his more general comments about prejudice could apply to any racial, ethnic, religious, political, body-morphic or sexual minority. When it comes down to it, "[t]here is not a candidate or major public figure who would not sell" ANY of us down the river, and most of them of both major parties have done so more than once in recent memory.
