Most people think they deeply believe things, and that there is some kind of ultimate truth which cannot be negotiated. One comes to see themselves as an extension of a shared identity within a given ethical, moral, and theological/philosophical construct. People believe themselves to be superior to others who almost believe exactly the same thing as them, but not quite, they didn't 'get there'.

It's extremely exhausting, and so you have to go to war with these people, time and time again, because they are deeply self-centered and passive-aggressive. Or aggressively passive-aggressive (backhanded(.

Because there is a flow. There's just this fliw, and things are obstructing the flow, as if they can make the stream reverse course by swimming against it.

It also helps if you have a Messianic, apocalyptic conception. Jesus didn't believe in a Messiah, he thought he was one (or he was, whatever, however you see it is fine). That's way less offensive than believing in one. Either you are or aren't the Messiah. Otherwise, please stop it.

The other aspect is cruelty. People these days always talk about 'harm', which could be anything, properly defined, but real cruelty doesn't really need to be defined. People don't like that. So when someone wants to blow up your country because of it, don't be surprised.
