An Evangelical Atheist is a person that is an atheist and tries to spread atheism amongst theists. It is derived from Evangelism, meaning "Spreading Good News" as practised by Christianity. Due to the rise of the Conservative Christain movement in the United States of America and the increase of humanistic thought, along with the increased blending other many different religions, Atheism has become more and more popular. Evangelical atheist usually seeks to "convert" borderline theists, often by engagaing in debate with fundamentalists.

Atheist: Yeah but where is it? and how do i get there?
Theist: its under heaven, maybe under the earth. And you get there by sinning.
Atheist: OK, is there a tunnel down to it? can you show me on a map? do you have a photo?
