I agree with that point.

And I agree with the harm it can cause.

Next someone will do a series called 'The Duke Boys', w/o comics, just live action. The Southlander will be the celebrated hero that can do no wrong. And the cultural shift might start going in that direction.

Yet I don't see a better way out of that, to drive humanity/culture forward. You need people to evolve, and you can't really do that without education.

Having racists brainwashed into not begin racists isn't a permanent fix, or perhaps even a bad long-term fix.
(But it does make the lives of so many minorities better for a time, which is huge, those are actual lives being lived.)

Pretending that racism either doesn't exist or having propaganda against racism just reduces the issue into a simplistic yes/no contest.

And social issues should not be treated as sports.
