disjointed fragments of sentences. I have a mental illness or two and am well aware how easily psychosis can take hold of your entire worldview.
I worry about how people who are "normal" do things I consider crazy, not because they speak directly to God, but because they are told by their preachers and other members of that community. It seems it is true that, "There is no thing a crazy person can do that can't be done by a sane person who believes."
I will go so far to include all people who believe in an "Ideal" be it heaven, a worker's paradise or capitalism. Ideals tend to encourage those who feel that the perfect "End" justifies any means (looking at you American Exceptionalism).
So before anyone goes on about Stalin, please note that there are political and cultural entities that operate as religions without god/s. Communist Russia being one example with Party Hierarchy taking the place of priests.
Let's not leave the Nazi's out of it either. Whilst you might be able to argue that a few members of the upper echelons were not religious, the vast bulk of the Nazi party and the German population believed themselves to be good Christians doing the Lord's work.
