They re-wrote Captain America to have a back story of 100s of black guys experimented on before they got to the formula for the white Captain America.
Most went crazy, become monsters, and/or were killed by the evil US military.
A handful survived, one of which is “Black Captain America.”
Typical liberal tripe.
Another addition to his back story: communist sympathy. They had Cap’s mom lose her house when he was a teenager, and the local communists help them move. Just a nice bunch of helpful people getting a bad rap from “the man”.
