Patton may have used blacks as combat troops in desperation, but the military wasn’t desegregated until the Korean War. In his own words (”War As I knew It”?) Patton stated that blacks couldn’t think fast enough to be used in armored units.
WWII will be minimized because blacks played no leading roles; one feel-good movie made around the time of (and probably in response to) the Crown Heights riot in the early 1990s showed black troops liberating a concentration camp - but it was fiction. The white troops who had actually done that were very vocal about it at the time; their accomplishment had been revised for political correctness.
The USA went to the moon, but it was a “white thing” so I doubt the history of the space program is even taught. If it is it probably give the credit to German scientists.

Yeah, black troops were in on the liberation of Dachau. Revisionist BS works both ways. You do us no service by giving the finger to the black men who were in our military in WWII.
