Atheists believe there is no god, that is all there is to being an atheist.
Meme is about religion, many do not follow religion but still believe in god. ;)
Meme is very accurate, there is no denying all mentioned was caused by religion... see comment below.
And yet atheist governments in the twentieth century still committed mass murder on a scale never before seen. You have completely failed to address this.
No, your stupid, bigoted meme claimed the moral superiority of atheists (who, by the way, committed the biggest mass murders in all of history) to religious people. I'm demonstrating why that is a risible claim.
