Greta Christina, the popular lesbian atheist blogger has a great article titled ‘Good Cop, Bad Cop: Atheist Activism’. You can find it here: -
She also recently drew a very good comparison between the LGBT and atheist movement, here: -
Her basic advice is that atheists should encourage, ‘coming out’ as much as possible, but follow it up with support, not just on line, but by actually joining a freethought organization, going there and meeting new ‘out’ atheists.
The biggest downer she advises against is to ignore the non male, non white community. It’s excellent advice and worth the read. So, hug all atheists, but especially female, black, hispanic and aisian atheists. If you are a female, black, hispanic, or aisian atheist, then hug yourself. But not too much because you know every time you do, god kills a kitten.
