I'd somehow missed the whole "Creepy Elevator Guy" story, but my son called yesterday to bring me up to date. For those of you who don't know, women are badly underrepresented in atheist groups, and the few who do attend meetings sometimes get unwanted sexual attention, which occasionally turns into harassment. In this instance, Rebecca Watson got on the elevator headed for her hotel room at 4 AM and was propositioned by one of the male attendees. Hemant Mehta has an excellent summary of the details so I won't repeat it here.
I don't have a lot to add to what's already been said. Blag Hag had a good blog about it. PZ Myers blogged about it and got a rather disturbing letter from Richard Dawkins, and Hemant Mehta wrote a second blog that was very thoughtful (he has links).
A while ago I wrote a blog that's very relevant: Mormons and Animals: Denying our Deepest Instincts. Men can be total jerks and worse. But atheists have a huge advantage over religious people because we can admit that we have base animal behavior. But where religion tells us we're sinful for having these feelings, atheists can face the feelings honestly and try to do better.
So here's my message to Richard Dawkins, in the form of a fantastic old clip from MadTV. Be sure to watch it to the end – it's brilliant. (The video doesn't allow embedding, so when you click the image it will take you to YouTube.)
