I sometimes think of starting a quote:

"Half of Western culture was created by the gays .... and the other half by the Jews!"



Um, *OF COURSE* this overgeneralizes and isn't strictly mathematically true (what about women and blacks and straight white christians/catholics). Yea, yea, it's meant to be a bon mot, a witticism, ok. Really though they generally have made a disproportionate contribution and that's the kernal of truth in it (and I'm not even sure what we are going to make of the ancient Greeks ... ).
