Attacking or making fun of someones ethnicity or culture is racist. And if I see it, I will call it out 100% of the time.
Like the picture someone shared a bit ago mocking a certain US Representative and the fact that she is Muslim and calling her shit for brains. (I will NOT share any more details about the picture than that.)
But if you see the picture and you think it’s funny, then maybe you’re part of the problem and a good, long look in the mirror might be in order. . .
