Skin color, along with all of the other non-critical details a person can have, is the reason that mainstream ideas hate people like me, my wife and my children. So, I would say that propaganda about "racism being wrong" should be subtly looked at - to make sure it isn't some crock-of-shit virtue signaling. Is it wrong? Yeah. Do all people display it? Yeah. At some point or another, they display all the -isms. Just takes a real enough reality check.
