I'm simply willing to acknowledge the good in certain tribes, and then go on to acknowledge the fact that modern "civilization" has disposed of that good for something lesser.

Modern civilization has done much, much more than any tribe. Tell me, did any of these tribes have democracy? Of course not, that's a Western idea. Did they enrich themselves with diversity? Of course not, they were ethnostates (alt-right values). They did keep an open borders policy, though, which I will concede is to their credit. Did they give equal rights to minorities? Did they use technological advancement to engineer a new and better kind of human? I can go on like this all day long.

If you want to say that stone age tribes were some kind of paradise, you're just wrong. Life was nasty, brutish, and short. Romanticizing them is folly. And yes, it is the noble savage stereotype, long ago thoroughly debunked.
