This. I think people underestimate how ingrained it is in US culture - in the early 20th century there were tons of minstrel show themed toys/knickknacks and racist caricature characters were everywhere.
No joke, I actually saw someone using a blackface mask in a high school play (rendition of the King and I) just a couple weeks ago, as part of the uncle tom's cabin play-within-play. It... it was a thing.
Honestly, about a quarter of that play in general was just kinda' screwed up. I think I had forgotten the thing was partially built off offensive caricatures.
Who remembers An American Tail?
