I'm sure black people don't like being told who they should support by liberal white people, and how they are stupid, or misguided, or whatever, for not supporting Sanders.
It seems pretty low to assume they don't have logical reasons for their current support of Hillary, or that maybe their reasons are simply invalid and/or wrong.
I guess people with some political preferences also wish white people to vote like they "want them to" and its not the issue of race. I know a lot of people who think in the same pattern like that in Poland where we have almost no black people. That might be a little bit clueless but not racist.
Still, a "corporate whore" fits a sexist definition (when you put a "woman" and a "whore" in one sentence, implication is rather clear).
It's not so much sexist as it is flat out rude and disgusting.
