Problem is it's often the literal Hitlers who think they're all pure and righteous and got nothing in common with him. They're the first to tell you that there is nothing to worry about and how the left are overdramatizing everything until fascism is the new normal. It's important to know that you can't even trust yourself to not have a Hitler inside you. Others will have to make that judgement for you and they can also be wrong.
So maybe there isn't a Hitler in everyone, but he could be in anyone including you and me.
If it was a core directive it would just delete itself.
