Yes, I did look it up before I wrote this, but why? What's the point of including some disadvantaged people and not others?

What problems do Black people share only with indigenous people that are not shared with all the world's disadvantaged people?

Surely Black people are people of color, anyway?

Latins are not necessarily people of color: https://en.wikipedia.org/wiki/Person_of_color#White_Hispanic_and_Latino_Americans

Inventing all these names we're supposed to know is not something that endears us on the left to anyone else.
