Read the freaking post.
Yawn. It's difficult to take this seriously. I'm sure you're smarter than this.
What I'm saying is that, given the cultural context, equating a black man with a non-human primate carries with it the meaning of that association in generations past, inextricably including its usage to depict people as subhuman, regardless of the intent of the speaker. Favors using such imagery does not remove the cultural baggage. Pretending that this baggage does not exist, or that it applies equally to white and black people, is an great example of white privilege. It's not racist to say any given white person looks like a monkey, because white people as a group have never had the term "monkey" used to deny their humanity. It's racist to say any given black person looks like a monkey, because black people as a group have had the term "monkey" used to deny their humanity.
What I find offensive is the idea that if Favors says it, then it's racist, because these events must be interpreted through your lens, which states that comparisons to primates is reserved for the black man. You must feel pretty strongly that an inappropriate idea must be applied on the situation because you can't seem to desynonymize primates with black men. It is ironic that you invoke white privilege as it is conveniently what's kept you from having any insight into your own feelings on black people and primate comparison, despite your professed distaste for it.
If anything, this should support many of your conclusions as evidence that the most advanced thinker on race among us still suffers from deeply embedded thoughts of dehumanization of the black people. The lack of insight should be quietly reassuring to the cause.
tl;dr One black man likening another to a primate must be a statement on race because it would be unacceptable to desynonymize blacks from primates. It is apparently the black man's station in life to be always associated with primates.
