Atheism is a belief, or even a faith, that there is no God, there is no religious higher power at all. George Carlin didn't call himself and atheist because atheism is a belief or a faith that God doesn't exist. Technically, that would qualify George as an agnostic which is my religious affiliation. I know so little about religion that my knowledge wouldn't fill a shot glass. But I do know that agnostics don't know if there's a God or not. That is different from believing one way or the other.
I don't give a damn about people's religion, including Atheists. (Sorry Bill Maher.) Just keep your religion out of my face, especially, if you believe your religion tells you to make the lives of other people miserable if they commit certain acts of which your fundamentalist tight ass doesn't approve.
As for you fundamentalist Atheists, people who are not only not religious but put down people for being religious even if they are good decent people, learn something about the First Amendment.
People have the right to be religious or not and to say whatever the hell they want to about it. Live and let live and your life will be hell of a lot better even if you're going to hell for not believing in God. If you believe you should get on fundamentalist Christians because you don't like their politics, keep in mind that fundamentalists Muslims are just as far to the Right on cultural issues. Maybe you should spread your hate to them as well.
