It always makes me laugh/irritates me when theists be like “Atheism is bad because Stalin//Mao was atheist. uwu”.
The fact that they might have been atheist and did something bad doesn’t mean they did it “in the name of atheism”.
Absolutely! This!! That’s one of the arguments that I hated hearing even when I was still a Christian.
Especially since, if we’re judging belief systems by the atrocities committed by the people who subscribe to it, Christianity has too much blood on its hands to throw stones. So even if someone did do something in the name of atheism, that wouldn’t reflect on any other atheists. Unless Christians would like to take responsibility for the many and varied genocides they’ve funded and led.
