> Racism is the belief that one race is superior in some way or another

What's going on is discriminating and prejudicing on the basis of race.

We can call that racism or anti-racism or peanuts & bananas, it doesn't change what the thing is. A person being advantaged or disadvantaged, being treated differently, on the basis of the race, something they had no control over nor consent to.

Treating someone differently on the basis of race is illegal under civil rights laws.

Because it’s the racism we were trying to end, during the civil rights era.

I understand many modern racists try to change the meaning of “racism” to except their repugnant behavior.
