you are ridiculously selective about what things we don't find in nature that you object to. get off the computer and go live in a cave. the smallest tribe is a family. we'd have none of what we all take for granted in modern life without much more pluralism than your tribalism would allow. it's the same myopic mentality that pretends there wouldn't be horrible repercussions without government or if we let religious thinking run shit. simpleminded bs to grift, who cares who gets hurt.
