Let me ask you an honest pair of questions. Yes, of course there will be follow-up, though it may be several days before I can spare a few minutes to return to this. Here they are:
Has religion contributed any evil to this world? Please cite examples, and be fair.

Has atheism contributed any evil to this world? Please cite examples, and be fair.
Not that I know of, but I assume you’re gonna refer to the Communist regime of Stalin. As far as I know, the actions of Stalin were not committed in the name of atheism, he did it because he wanted power. Stripping people’s religion from them was an effective demoralization tactic, so that’s what he did. And it’s not like communist Russia was a godless society, their god was the state. Bear in mind, I don’t know a whole lot about communist Russia.
