Others may cherish this stuff as a tribute to free thinking or whatever, but I’m happy to see the lack of distribution as a sign we’ve learned some things. This isn’t Chesterton’s Fence or the Mona Lisa, this is just racist humor aimed at boomer kids.
It's also literal whitewashing to take all of the black people out of the past, even if white people depicted us as clowns and monsters. I should be able to say "your grandfather depicted me as a clown and a monster." Better than being a problem swept out of frame.
The WB content is aimed at kids, and I think that makes a difference.
For that matter, I wasn't even criticizing the OP document for missing those eleven. Given the time it was written it's quite possible the author didn't even have access to them. In any case, the omission of those few from what seems to be an otherwise comprehensive document is, I thought, notable.
