1 - Most notably, as a gatekeeper in startup culture (<- this seems to be causing confusion: not a gatekeeper to doing a startup, but a gatekeeper to YC which can often be important in succeeding as a startup in my and many other people's opinions), it seems pretty willfully ignorant to assume that you'd know if you were biased against female founders because if you missed some you'd know. If women are a group that starts on the outside to, as a gatekeeper you'd need more than that to know if you're keeping the gates properly, since we it'd be pretty hard to argue the system as a whole isn't a boys club.
