What “idiots complaining about cultural appropriation”? It’s not exactly a common thing, despite what caricatures of them might make you think. No one is getting upset that anyone eats food from another culture.

The only actual examples I can think of that I’ve actually heard discussed are “please don’t dress as my race as a costume, it’s basically blackface” and “my religion was systematically driven to the brink of extinction, I’d appreciate it if you didn’t use it as a fun activity to express your creativity”.

These things always seem chock full of getting defensive about something that doesn’t really happen, or acting like the smallest pushback to the dominant culture doing whatever they want is incredibly terrible.
Appropriation isn’t an issue when it’s just cultures sharing. It’s an issue when people reduce the culture to the things in question, forget that there’s actually people involved who deserve respect, or outright claim ownership of the thing in question.

Don’t go to a Halloween party dressed as a Puerto Rican. Don’t grab a random assortment of native American religious practices, mix them with crystals and use it to showcase your creativity.
