Really? Do you have to be so patronising?
I am a graduate in social studies, it is not good for much but probably helps me understand what racism is & how it effects those involved.
Let me give you an example.
A football player would probably prefer the racists in the crowd to not throw bananas at him, this was quite prevalent in the 80s. Of course there are still racists in the crowd but they are generally shamed into keeping their mouths shut; this is a good thing.
The early stages of educating racists is, perhaps, for them to keep their poisonous views to themselves.
I am not saying this is perfect just less harmful.
