The roots of atheism are always moral not intellectual.
Roger that, and in a sense atheism is ultimately self-worship, worship of the ultimate false god. So in essence, atheism is idolatry. It’s not truly that they don’t believe in any god. They appoint themselves as their own personal god. Worship of any God outside themselves is therefore blasphemy as far as they’re concerned. That’s what really gets them bent out of shape.
