And Stalin was an atheist

More accurately, not only that but if Dawkins murdered a bunch of people for believing in God and shouted "ATHEISM IS THE ONE TRUE WAY", there'd be a point. Essentially how Albania had state atheism for many years with a high level of persecution of religious groups because they were religious (rather than heretical of the Glorious Leader's ideas). It really has to be in the name of atheism for it to be the case, if Dawkins suddenly went batshit mental without specifying a cause, we may as well say that it's evolutionary biology that caused it, not atheism - we can't privilege the hypothesis that it's atheism.
