I do not try and convert because I am an atheist. I try and convert because I'm an anti-theist and less specifically anti-faith. I belief that faith and religion are terrible problems for mankind that lead to crimes against humanity and an atrocious waste of human intellectual and physical resources. I am happy to use the tools beloved by religion (evangelism, polemic and emotional appeal) while rejecting the principles of religion (sin, division and moral absolutism) to do my best to make the world a better place.
This is the dream :) - get over here and check out rationalism and stuff.
