I watched
CSA: Confederate States of America. It is an alternate-history "documentary" about if the US Civil War was won by the South and thus slavery was never abolished. At times I thought it was going into "the South is inherently evil" territory, but at the end it tells you which bits are historical trufax and I think by then I had got in tune with it's premise that if you have racial slavery (or slavery in general?) it makes other things a lot easier. It has brief mentions of the impact on gay and women's rights movements (they don't happen, pretty much) and I think it is good for showing just how much one struggle can help another. (If these people are okay, maybe these people are as well.) I feel I have a new appreciation of this, cos I have always been interested in struggles against The Man but had not thought much on how taking away one takes away what others have to build on.
You may find it whitewashes Britain/Canada a fair bit, though I admit I was too busy being confused that Canada was the Good Guy in an American film. It may be too easy to conclude that black emancipation stopped American imperialism, which in the real world obvs manifests via aggressive capitalism and support for dodgy regimes. I'm not entirely sure why Communism wasn't an issue for the CSA, but maybe it is arguing that society creates a scapegoat class (or several, as IRL) and only needs one enemy at a time?
Semi=-confusingly the Republicans remain the less evil party in this alternate history.
