Wtf did forced integration come from? There’s cultural variation everywhere and it rarely corresponds with political borders (or happens as a consequence of it I suppose).
Not really. In a whole number of ways. I actually have no idea how you can say this with any honesty.
I mean, are you really arguing that national identity is the major stumbling block in integrating to a tribe in Papua New Guinea.... Here's a hint: Other :tribes: would have difficulty integrating, and they've likely never been introduced to the concept.
Please explain to me how you're so confident while simultaneously so widely and clearly wrong.
For example, you should be able to walk into any Native American tribe and be able to seamlessly integrate yourself into their culture despite having zero background.
