I think what Enginerrrd is calling psychotic is that there's no way to, as you say, "make someone part of the same tribe" without employing a great deal of force to coerce (and crush) people.
You know, when a president says "we gotta unite the nation" in a speech, that's kinda what they're trying to do. Except just saying "oh yeah, let's unite" falls quite short of achieving that goal.
But no, it's not about coercing and crushing anyone.
