I'm not saying Graham should drop everything until every last bias is gone. I'm saying he shouldn't act as though sexism is a solved problem at YCombinator just because the percentage of female founders is up and it has women as partners.
I believe the standard request is:
> "If there was just the pro-activity line of attack, if it was like, "OK, yes, women aren't set up to be startup founders at the level we want." What would be lost if Y Combinator was more proactive about it? About lowering standards or something like that? Or recruiting women or something, like any of those options?"
Edit: He is willing to do more about the problem generally, and I give him credit for that.
