Well, since "racism" is a 20th century neologism with no fixed meaning, you are both right (using your definition) and wrong (using the narrative's preferred definition).
What you SHOULD be disagreeing with is using words with no fixed meaning at all.
Here is an article of a guy who collects a lot of antiques
He might have gotten some of collection is illegal manners, such as digging up burial grounds
The money shot quote is here
“We have to think about the context of: Who has been the target of grave robbing for centuries? Whose ancestors have been collected for hobby?” Cusack-McVeigh said. “And this comes down to racism. They aren’t digging white graves.”
Yes, they invoke racism into EVERYTHING, its insane. It is almost like the word means nothing like you have stated. A guy collecting certain items through grave robbing and he only looks for Indian (native american) burial grounds, isn’t a racist because he doesn’t do it to white burial grounds.
