The story goes like this:
The whole world knows that there is racial discrimination in the United States;
Americans themselves know that there is racial discrimination in the United States;
So american movies directly made to tell everyone that there is racial discrimination in the United States;
It is equivalent to shouting to the whole world: we have this thing.
Can you change it, again. Admit it anyway;
When to change, I can't tell. Anyway, it has existed for hundreds of years, not much news;
To make a movie is to tell you, I can't control these movies, in the end, we are going to see it for yourself.
Well, we don't have any on our side anyway, and there are no other messy things;
Oh well.
