Yeah, I've read through most of LessWrong's "gender wars" last year, and I'll stand by the statement that most LW contributors don't hold the attitude Jandila critiques.

Specifically, the impression I get from Luke's post is that his study of rationality over the last couple years coincided with his study of his own attitudes/feelings/decisions in the realm of romance, and that he was eager to make the connections between the rationality skills and the specific example of his dating life. Unfortunately, he stepped on the anthill of LessWrong gender resentment (which goes both ways: those annoyed by the stereotyping and those annoyed by the other ones for getting annoyed so easily). Reading him charitably, he made observations about his own life without intending anyone to generalize. Reading slightly less charitably, he's internalized a couple of stereotypes to the extent he didn't even realize that they were stereotypes and that he would invoke them.

Either way, I think sexism is very rare on LW, and stereotyping that can lead to inadvertent sexism isn't uncommon, but also isn't typical.

apparently if you try to comment while offline / having connection issues, it locks the post from copying/editing, and there's no way to try to repost it, argh
