Normally a good article gathers a whole bunch of information, and tries to put the puzzle pieces together. That is objective journalism. Information before the theory.
The article you posted all points in one direction. In this article the theory was made first, and the racist remarks found second... explaining why it points in one direction. The cart is very very obviously before the wagon.
I see no reference to any positive statements by any influencial people of color in this article. Not ONE! This would at least show some objectivity.
This article is very very very obviously nothing more than Fearless Hate Mongering. It generalizes people of color as a bunch of people who hate and want to kill white people.
As for conditioned programming... that is exactly what this article is. The proof is in the pudding.
