I see at least three different topics here (maybe more could be found in other articles and discussions) -- speaking of women as objects; unsupported or incorrect theories about differences between men and women; unfriendly environment -- and I believe each of them deserves to be discussed separately.

I think the assumption here is that LW is some sort of a sealed environment, living in a vacuum only of its own generated ideas. Needless to say, it's not like that: everybody will continue to bring here, rationality or not, basic imprinting from life AFK. This includes other-sex objectification (let's not illude ourselves with thinking that one side is less wrong than the other), incorrect thinking, etc.

I agree though that if we are not able to win on gender issues, we are doomed.
