I agree. However I still don't see how a "dongle" joke (regardless of conference policies) makes it to "sexism towards women" as appeared on the Richards' blog. I think the point is to say "I myself am not comfortable with this kinds of jokes, stop it". But making gender generalizations and "taking actions for the community"... well, this is sexist towards women and assumes no personal responsibility. I'm a woman, but I didn't appoint any "evangelist" to speak for me. It's actually more alienating then any off color jokes.
