Incredibly easy to search for this. Prison labour in America through the 13th amendment is certainly wrong but nowhere near what North Korea does. Look up Yeonmi Park and her story. A North Korean defector, she would know what happens when people fail to please Kim Jong Un. Entire generations of families are taken and worked to death, from pretty crimes like burglary to the heinous like not being sad enough when dear leader dies. Attempting to equivocate the two disproves that theory.

Second, https://en.m.wikipedia.org/wiki/Uyghur_genocide Like come on there's so much documented evidence of this atrocity. I don't trust death rates on either side, but if the estimation of 1mil+ Uyghurs are in detainment camps, that's still about 10% of the entire people's being here for political reasons. Whether it's a human genocide or cultural genocide, its still wrong and immoral being spear headed by an evil totalitarian regime.
