All this having been said, I think that the level of vitriol PG has been subjected to is completely unfounded. I think it's unclear whether YC is morally obligated to lower its standards for female applicants, or to make special efforts to encourage them to apply. The first is fraught, since it implicitly means you're selecting less-qualified people over more-qualified ones (the Ivy League universities do this for disadvantaged minorities, Caltech notably does not), the second would be nice (and I think basically all top-tier universities in the US do this for disadvantaged minorities), but it's not clear to me that it rises to the level of a moral responsibility.
