But then how would the OOP's example count when pixar didn't claim culture?

I asked this question because i'm super confused after watching the beginning of this video, which sort of match what OP said.

I also heard some people define it as purposefully misrepresentation of a culture or ethic, which tbh is bad(like how hollywood movies often portray some country) but it doesn't seems to be what most "cultural appropriation" are about

There's also another famous example from 2018, which an american chinese accusing a white highschool student for wearing qi pao as a prom dress, which funny enough, got the approval of asian chinese after the fiasco make its round. In my country we wear each other ethnic's cloth often, no one have any issue with it, it's confusing why it's such a sensitive issue.

There's of course very bad actor out there but a lot of times it's a head scratcher for me.
