I think you didn't understand my claim. My claim is simple, my long explanation above was meant for you to arrive at these conclusions yourself:

* people are nice when they still behave in the old, tribal way.

* the tribal way is always going to be creating individuals who are racist and conformant/conservative.

* not behaving the tribal way means going outside the conformist mold, which means you take risks and eventually learn by experience that taking more risks come with consequences. You become less trustful of everyone, while almost paradoxically proclaiming yourself to be more open.

This fits observation. If you believe it's wrong, you must demonstrate why with supporting evidence without contradicting the evidence I've used, obviously.
