What less than desirable traits promote survival?

[Rev. Rye]

The same impulse that leads to bigotry probably evolved out of a self-preservatory instinct and halfway-decent method of managing our Monkeyspheres. Trying to care about everyone is really hard, and literally the best way you can overcome it is by just caring about large groups of people in the abstract. If you can try and limit your tribe, the whole thing becomes a whole lot easier to handle. Innocent people get fucked over by it? Well, they're not part of my tribe, so it's not my problem.
