I'm of mixed opinions about him. On the one hand, he's been influential in making Pycon more friendly to women, which I support[1]. On the other hand, he appears to have swallowed the feminist kool-aid without reflection. He has a knee-jerk reaction whenever an alleged case of "sexism" comes up - he is inclined to take the side of the "oppressed" group and facts be damned. He takes a guilty until proven innocent standard for people with a Y chromosome.
