I don't think the generated quotes are very good. To me, atheism is not a way of life. I don't go around "not believing in God", in the same way I don't go around "not believing there is a chocolate teapot orbiting the sun.". Neither is atheism being free. You can be atheist and very unfree.

The quotes read like how a religious person who came to atheism might feel, I guess. They are certainly not how any atheists I know would describe it. Mostly it's not there at all.
