I got a suggestion from my algorithm on YouTube for a mashup video of John Cena's "My Time is Now" and Eminem's "Encore/Curtain Call."
Encore was released is 2004. The song includes the following lyrics
Spoke to a generation of angry teenagers Whom, if it wasn't for rap to bridge the gap, may be raised to be racist Who may have never got to see our faces
Eminem is saying without rap, white kids would just black people. That rap gave them a reason to empathize with blacks.
The idea being blacks and other minorities are naturally empathetic and not racist, conversely white people are naturally racist and hateful.
Where does this attitude come from? It's clearly not backed by any data, because data shows white people don't tend to have high in-group preferences. Especially compared to the preferences of other racial groups.
From the people who orchestrated WW2. Germans weren't the only target for reeducation after the end of the war. This attitude has been brainwashed into people for the last 80 years and counting by what was once the Psychological Warfare Division.
