So culturally powerless people may extract from culturally powerful people until what point? If a Ukrainian appropriates a part of Russian culture to be their own, who is the victim here? Recently, being Ukrainian has become a much more respected cultural identity than being a Russian, does that mean the power dynamic has shifted?
The more you pick away at the idea of cultural appropriation, you realize that the rules people set out for it make very little sense outside of the egregious examples of something like headdresses at Coachella, etc. My personal rule is just not to disrespect people and parts of their culture they find important. The color of my skin or the actions of either of our ancestors shouldn’t play into it, IMO.
