Disclaimer: I am not trolling, I am an autistic person who doesn’t understand so many social nuances. Also I am from New Hampshire (97% white), so I just don’t have any close African-American friends that I am willing to risk asking such a loaded question.
America is not the world my friend. I mean Irish people in Ireland have been historically repressed and reviled in and by UK and Europe. I dont know how prevelant it continues to be, but there is a deep history.
Humans beings the world over find ways to categorize and class each other on ethnicity in all sorts of ways that is fundamentally working with similar power relations to racism without it being reducible to skin tone.
