Some ideologies are, in fact, mutually exclusive and cannot tolerate the others. Fascism cannot be tolerated, for instance. Nor can a belief in chattel slavery as a universal good. Sometimes an opposing ideology is just too fucking evil to be allowed to persist.

Setting the line that must not be crossed is a hard no problem though. And misplacing that line an inch incorrect in either direction can be horrible too.

I think you could rationally explore ghosts in the “radically redefining” them arena. Ghosts could rationally exist as an artifact of your mind, and saying that is not the same thing as saying they don’t exist. Hallucinations exist. They aren’t real, but they exist. Ghosts could rationally exist in the exactly same way, as processes in our own heads. It’s when you start saying they interact with the world in a way outside people’s heads that you can’t really reconcile.
