When it comes down to it, evolutionary biology itself seems to have a pro-segregation and pro-violence subtext. Does that make it wicked? Gangs have some tribal features, as you note. They miss being truly tribal by lacking biological continuity; that is, their members are recruited into the group, not born into it. You ask if Leaver peoples can exist in harmony not just with the world but with each other in multicultural peace. Conflict among Leaver peoples is not “multicultural war,” so who says they do not enjoy “multicultural peace”?
