At the American Atheists Southeast Regional Atheist Meet (SERAM), there was a panel discussing submitted topics. One topic was about the treatment of women in the freethought community.
I don't think I have anything especially insightful or persuasive to say about this, but I will express my opinion that the whole panel was deeply disturbing. The panelists seem to think sexism is some kind of joke.
There's a big fuss in the blagotubes over this incident, spawned by a guest post on Blag Hag. Opponents are complaining that the guest post exaggerates some things, but I think that's missing the forest for the trees.
