> So you say, but history has shown that if groups don’t exist to allow easy discrimination, they will be created to allow such discrimination.

Yes, that's what I am saying. In- and out-groups are made contextually in each unique situation.

> So it’s a good sign of long, well established, and ingrained discrimination, eh? With associated infrastructure to make it easier to continue, and ‘fairer’ in that it allows almost everyone to have someone under them to take their own angst out on. (Except those ‘outside the system’ anyway, which historically were the Dalits, but now even they are in the system eh?)

Can't understand what you're trying to say here.

your thoughts seem to align closely with René Girard's theories on mimetic desire and scapegoating.
