Here are some excerpts from that discussion.
Feminism is about breaking down arbitrary barriers.
I think about all the limitations of opportunity that people experience because of arbitrary difference like race or gender. Just because there's an arbitrary rule, we're not going to let you do certain things or be certain things. We're going to limit your education and work, and commit violent attacks on you because of some arbitrary external characteristic. There are lots of parallels between racism and sexism. No, you can't act that way or go into that profession because you're female.
