This might be of interest, as the issue of activism is obviousy relevant to anti-theism.
I was recently irritated into activism, if only on a very mild level: after a number of random strangers tried to convert me to their beliefs in a short space of time, I decided to produce an ‘atheist pamphlet’ to exchange with these people in future (seems only fair that I should 'give them something to think about' in return). I had always wanted to do it (people who call to my house, interrupting my work and invading my privacy, irritate me especially), and I decided enough is enough - I'm fighting back. I want to demonstrate that theists are not the only ones who actively promote what they believe to be right. You can find my leaflet at http://atheistprinciples.tripod.com
Comments would be much appreciated.
