Remember, it's not whether it's racism, it's whether people are using political party association against other people based on the color of their skin. That happens, and the Joe Biden example is a perfect example of that. He had clearly assigned black people to "his camp" as a group. She's saying 'don't group us based on our skin color and let us have our own opinions without being belittled on account of our skin color.'Neither of which is racism. Proof, yet again, Conservatives are clueless on the definitions of the words they throw around.
That's all. Her message is on point, and the Biden example is a great illustration of the antithesis of her vision.
