Cultural appropriation is something that will happen within cultures that show interest in other cultures. It's inevitable.
The fact that our culture is having this spirited debate about cultural appropriation as opposed to appreciation is a product of our having interest in other cultures.
I don't know how many people need to be lectured on this; but, it seems like a lot.
There are a lot of cultures out there that have no interest in other cultures. In fact, there are cultures that are downright hostile and violent toward other cultures. They tend to remain primitive because they don't learn from other peoples and assimilate.
Cultural appropriation is a dumb thing to get pissed off about to begin with; but, once you understand that a prerequisite for cultural appropriation is curiosity, it becomes even more absurd.
