everyone (else) seems to be hating on atheists

[Ace Otana]

I hope not given the fact that Marxism is atheist by definition.

Got to make something clear to you (and I know it won't sink in).
Communism is a political stance, theism and atheism are stances to do with belief or lack of belief in god.
So quit trying to merge them.

I can mention thousands of religious leaders who have committed mass murder and genocide if you want? All in the name of their religion/god.

I used to have an extremely long long long list of atrocities committed by religion, the church and religious leaders. Looking for it now. It's a hell of a long list.
Hundreds and even thousands of atrocities have been committed by religion, I could easily say that it's proof that the religious are immoral. I can produce a far far far greater list of mass murders and atrocities committed by religion than you can for atheism.

If Christians had killed and suppressed tens of thousands of atheists just in the last century you might also have the energy to rant.

Well.........they have actually. I could start with the Catholic extermination camps. Over a hundred thousand stabbed, hanged and burnt alive. Which happened within the last century.
