Sorry, but why are you telling us all this? Yeah, feminism is pretty interesting (at least it interests me) but why are you giving a lecture on it? It would seem that most people interested in a spontaneous intro to feminism have already received it, and are currently picking nits with the five-sex model of intersexed people or post-third-wave developments.

(...plus, c'm'on, second-wavers totally sucked at telling gender from sex. Just ask Bindel or Daly about trans women.)
