It would be pretty easy to argue that the AP is practicing racism as well here. The article is pretty absurd as well. Their argument is they are not capitalising the word white because white people have not faced discrimination and it would legitimise white supremacy. Without debating either of those points, how are they relevant to grammatical rules. The words are either proper nouns or they are not.
