Like genuinely, imagine creating a setting where a hyper xenophobic racist caricature of 1910s America is completely isolated in a floating sky fortress and run by a openly racist pro-slavery dude (in the 1910s btw) who is also worshiped by the people there as a messiah, then having a bunch of blacks, jews, chinese and irish all magically show up there just so they can be perpetual victims of whitey over and over in the story and background until they break into a giant pseudo-communist "revolution" race riot.
The ONLY explanation they give for why black men are there is "er um well uh they needed cheap labor so they imported black convicts from Georgia", which doesn't explain how the black women and other races got there but is also completely fucking nonsensical because Columbia has fucking robots and superpower juice.
Why would you, as ultra-racist white-nationalist isolationist religious zealots that follow klansman Jesus, import black people to scrub toilets and break rocks like a chain-gang when you have literal robots walking around (and infinite-energy quantum generators powering your entire city), along with superhuman juice in bottles laying around?
I can't believe people actually praised this shit when it came out, it's fucking awful.
