How do you do something “in the name of Atheism”? You are being pedantic. These were/are crusades against the culture and faith of a different people. One could argue that they are not “genocides” and it needn’t even be in bad faith. Your “assuming 100% accuracy”-statement on the other hand disgusts me, no offense intended. People are suffering, at least aknowledge the fact.

You’re being dishonest. The definition of the words rules out the undesirable conclusion. People can’t do anything in the name of atheism.

If “Religion poisons everything” then removing the poison should rehabilitate the patient, no? So please demonstrate that secular societies are more benevolent than religious ones. Show me that those who invented industrial murder are morally superior to ad-hoc killers.

Did you know that the word genocide was coined to describe the actions of a government who was actively trying to secularize?

Well you could argue they aren’t just like you can argue that religious genocides aren’t about religion but really about money and power.
