I agree with everything you said but I’d also like to point out that it wasn’t just a form of comedy, it was an entire entertainment industry all on its own, like movie theaters or concerts today. It was called the Minstrel Show
It eventually got replaced by/morphed into Vaudeville which was then replaced by cinema.
For a good 50-100 years, a major form of entertainment (not just in the South btw) was pretty much just: “haha black people are such stupid clowns! Look, that one thinks he’s fancy! That one’s a no-good drunk! Oh look, that one’s trying to give a speech!” It was pretty formulaic with standard props, just like you’d expect to see at a clown show. So fried chicken and watermelon were standard props like “tiny car full of clowns”, oversized shoes, a flower pot for a hat, a flower that squirts water, etc. For that reason they carry a very unpleasant legacy that reminds people of an insult to injury that still hasn’t been made right, in my opinion.
The format was pretty similar to the show Hee-Haw actually, kind of a fun variety show, just wildly racist and it’s obviously pretty fucked up to pick on literal slaves. Real bitch move there.
So people who know something about history are pretty salty about that and forms of the Minstrel Show were still happening here and there recently enough that people alive today remember seeing them.
Irish people caught some shit, but not like that. I’m not sure if Irish-American racism like that happened recently enough that living people remember it, or that it was ever to the extent that it formed an entire entertainment industry.
