How to destroy any argument for God

[Mister Agenda]

Atheists killed 100 million people.

Telling non sequitor, though I happen to agree that calling all religions '100% pure evil' is ridiculous, and particularly unfair to Jains and Quakers. But if you are a Christian, you have far more in common with Hitler, Torquemada, or Osama bin Laden than I have in common with Mao, Pol Pot, or Stalin. All I have in common with the latter is my lack of belief in a God or gods (if they were, indeed, all atheists; some of them had a funny way of showing it); I disagree with them entirely on politics, methods, ethics, pretty much everything significant except that one thing.

The former, however, believed many things that Christians believe: a divine creator, represented by Jesus, and much of the rest of the Bible. That's a lot compared to just an opinion on the existence of deities.
