I ditched out on LessWrong because of a strong and intolerable undercurrent of sexism in the community (as Neal Stephenson put it in Snow Crash, "the especially virulent type espoused by male techies who sincerely believe that they are too smart to be sexists"), but I think you're being a bit unfair to them here.
This whole foofaraw appears to be entirely due to Yudkowsky, the founder, and as far as I can tell the huge majority of everyone else there considers it almost as eye-rollingly dumb as you do, and quite an embarrassment.
