You have a lower bar for racism than I do.It does not matter what color someone is...calling Clarence Thomas "Uncle Tom" is racist...no other way to look at it.
characterized by or showing prejudice, discrimination, or antagonism against a person or people on the basis of their membership in a particular racial or ethnic group
NOWHERE in this dictionary meaning does it say "by white people only"
If I call one of my cousins an ignorant towelhead that's a racial slur but I doubt either one of us would consider it racism.
And gtfo with the white people only. Anyone can be racist the only requirement in my mind is someone of one race using a racially specific insult towards a person of another race.
