Its largely ba<x>sed on ignorance and yes it is wrong but i think sadly impossible to eliminate
It's easier to live life ignoring those who think they are superior to everyone else. What's the point? They'll probably never change.
It's still very deep seeded in our culture. We only abolished discrimination 50 years ago. It'll take a lot of time.
Who doesn't know that? The question is do they care? Or are they too busy thinking that their race is more superior to the other's - which, by the way, is the definition of racism?
