All Atheists are fundamentalists. The fundamental rule of atheism is the lack of No Gods. All atheists have no believe in any gods and that is the only requirement to be an atheist and if you have no believe in any gods you are abiding by the fundamentals. Atheism is a 1 string banjo and everything after than 1 pluck is up to the individuals. Christians have an entire book which mandates how to be a Christian along with organizational(church) creeds. Atheists do not need a book to tell a person what an atheist is.
What Christians want to be is attach things to Atheism like science and reasoning in order to demonize those things because Christians are not fond if science or any form of reasoning as are most religious people.
