No, I found it somewhat idiotic the argument that because Stalin(not Hitler, mind you) was an atheist, all atheists somehow share the bloodied hands. Note this, an atheist is to himself or herself. There is no connection between one and another, as the case is in organised religion.
Well Stalin also drank water. So are all water-drinkers evil?
People who argue against the idea of not believing in an imaginary being, based on that faulty logic for one, know squat what atheism is.
It’s generally understood that when people categorize- they aren’t doing so wholesale and are only talking about those of groups who hold extreme views and voice them like Dawkins does.
