He's right. A lot of people on the alt-right believe in group selection and race-based altruism.

Sorry, I meant that Yeyo is right, not Salter. Salter is probably wrong, but I haven't read the book.

I suppose that one idea pointed out in the links @BioDeterminist just put in this thread is that ethnocentrism can arise without "altruism"

Yeah, I should take a look at that book -- Axelrod is a smart guy. I am skeptical though.

Regardless, society is not based on shared genes, and racial preferences are easy to explain without kin-selection.

I agree, but you have to define "group" and take the cause-effect relationships between the group and individual into account.

That's why societies can't be based on altruism, and why communism always fails.
