Sure, but my beef is that many of the young activists I know use it as a term virtually synonymous with 'black person', which means that they end up ascribing forms of discrimination to POC which really only happen to say, blacks or latinos.
I think saying "police brutality disproportionately harms POC" is not necessarily a semantically incorrect statement (even if we're of the belief that, say, Asian people probably don't experience a disproportionate amount of police brutality) just because it doesn't apply to the entire umbrella of "POC"
Is that the kind of statement you're talking about?
