It’s more like:
“If you support Trump, then you didn't vote for Biden.”
So far so good.
“If you didn't vote for Biden then you ain't Black.”
Contextually, Biden was saying that if you don’t understand how Trump is hurting black Americans with his policies then you’re not black. He never specifically said only black people will vote for him. Just like Trump never said Nazis were “very fine people.”
“That's Black with a capital B - as in 'politically Black'”
This is close. While one’s blackness can be prescribed to their identity as a black person by whom and what they support, it never makes you less black but rather whether or not you’re acting in the best interest of the black community as a whole. A thoroughly problematic viewpoint to say the least especially if the goal is true racial equality. What they are afraid of is the whitewashing or watering down of black culture. Which is about as ludicrous as “white” culture fearing the black element that will erase or replace them. It is racist.
“Which means you must be a white supremacist, and so they can't be racist against you because of your political Whiteness.”
Almost. Black people, biologically speaking, can never be white. However, they frown on supporting anything against black culture. Not just in the shallow sense but in every aspect.
If black peoples can be racist; then black people CAN support white supremacy. Wittingly or unwittingly. There is a failed concept within politically correct terms that black people cannot be racist but by saying black people can support while supremacy; they are essentially admitting they’re wrong about black people being racist. Not just toward their fellow white people but their own. Which most assuredly DOES happen, which they admit in the concept of “colorism” which they will continuously say is “different” from racism. Except it isn’t. It absolutely is racist for black people to judge other black people by the color of their skin. Now is it the same equivalency as institutional racism? No. Colorism is about the equivalent as modern racism. It’s still discriminatory and in some situations can even lead to litigation but rarely does since it is often overlooked form of prejudice.
But prejudice alone is not why black people are statistically less likely to vote for Trump than they are for any Republican. Playing the victim doesn’t make black people more likely to vote for Trump.
I hope this clears some things up.
