I also find it funny that people say religion is the cause of all the worlds problems and in the face of the fact that the biggest mass murderers in history were atheists. Wacky fun times, I tell you.
I understand that many atheist individuals have done terrible things, for instance Stalin, or Chairman Mao, but they didn't commit, and I'd like to stress I'm in no way defending or empathizing the atrocities they were guilty of, their crimes as a result of being atheist. Dawkins makes this argument (not that I particularly like him), during his debate with Bill O'Reilly.
Additionally, Hitler was a Christian, but he didn't undertake mass genocide because of his religious beliefs (to my knowledge, I'm not a specialist on Modern History).
Digressing slightly, it appears that religion is the terrible excuse, or the means of control, by which certain men and women of notoriety, time and again, instigate war and racial hatred.
