I've noticed that people always call black people "african americans" even if their family has been in America for multiple generations (though I have seen more black people saying to just say black people now instead) but white people are just "white people" and not "european americans" even if they have recent ancestors who were immigrants from europe. Why?
Edit: I'm not saying that anyone should or shouldn't be called African American or European American.
Edit: Typo
To be fair, a lot of Black people in the US feel that the word "African American" doesn't really fit them. I don't say it, I've been informed by the people around me that it's better to just say Black.
