One progressive effort to wipe out racism today is to insist it's still omnipresent now but eliminate it from the past. So authors like Mark Twain, or even Ian Fleming, are shoved to the side if they examined the culture of their day uncritically. In the case of Mark Twain, even a black character who is clearly a hero has to be censored.
So it goes in film media as well. There is a Disney film you can't buy in the United States, but you can buy in England, because it is racist in the United States. Yet the English brought slaves to America, Thomas Jefferson instead made importation of slaves illegal in 1808. And they don't think it is racist.
