POC. Idk if this counts exactly since it started with bigotry then was reclaimed/euphemized
The part that bothers me is that it feels a little like I'm still being called a "colored person" just in a different phrasing, and later on, in abbreviation. I still call myself brown, white people as white, etc. without issue.
So I think it's more that brown people have always known ourselves to be brown, but not "colored" — that is a slur used by white people against us. Like in our native languages we have a concept of skin shade. But not "coloredness"
Also "POC" sounds a little weird to me, like how saying "people of brownness" or POB feels artificial and awkward.
Not really against "POC" though since people use it broadly already.
