Those views can go together, can't they? If you've never learned to accept the existence of things you don't like, and feel entitled to have everything done your way, you'll love people who are fighting for your side. If you also believe that "the others" aren't doing it because they are different from you but because they are evil and know better but hate you and all things that are good, then you'll especially enjoy the vicious and nasty attacks on them.
I don't think they could avoid each other, given that they're trapped within the same reality. If anyone manages to fork the simulation into multiple branches strictly divided by tribe, will they be happy places? Or will new factions form, and the process repeat?
