They will call it liberal bias, anti White propaganda, or flat out bullshit.
I have an older White executive who's fairly open minded but is completely unaware of so much of America's racist history. She also thinks the Black Panthers are the Black equivalent of the Ku Klux Klan. When I told her the The Black Panthers: Vanguard of the Revolution was streaming free on PBS last year, and you could get better educated on the subject, she straight up said that she's just not that interested in it.
And that's the problem, too many White people WANT to be willfully ignorant, because they already like what they believe to be true.
It's because Halle Berry was miscast as a fictional African Queen Superhero.
