I myself have never been able to find out precisely what feminism is: I only know that people call me a feminist whenever I express sentiments that differentiate me from a doormat, or a prostitute.
Prostitutes can't have good opinions? That statement is kind-of telling in itself.
OTOH, I just went and read about her a little and she seems like she was probably OK. Though I'm sure this quote was somewhat tongue-in-cheek
"There is, of course, no reason for the existence of the male sex except that sometimes one needs help with moving the piano."
There are two versions of the quote in different books, and the first just finishes at doormat. I think the idea with prostitute is that you expect them to say what men want to hear - she's talking about expressing independent opinion after all. She also said The main difference between men and women is that men are lunatics and women are idiots. - so she didn't pull her punches. Fantastic writer - George Bernard Shaw seems to have thought that she was better at it than him.
