Appropriation is a value-neutral concept. And also not rooted in exploitation per se. There’s an erroneous conflation here between colonialist appropriation which does material harm to the people being colonized as well as possibly being a component to the ideology of colonialism (like Israel taking Palestinian culture into itself to use as a justification of their superiority to them) which marxism will sometimes talk about, versus neutral appropriation like white people using synthetic peyote or American teenagers making vaporwave from '80s J-Pop.

It’s not inherently disrespectful to use things without chaining ourselves to the original contexts they were used in. It can sometimes be harmful and/or disrespectful but idpol liberals literally only care about turning anti-imperialism and morality into arbitrary dinner etiquette. So they just call it all cultural appropriation and tell people not to do arbitrary things.
