Absolutely a travesty, but still you're engaging in false equivalency. The difference in being jailed with or without some legal process is significant. Study up at https://freedomhouse.org/report/freedom-world/freedom-world-... and acknowledge that the US's score of 86/100 is a far cry from Canada's 99, but worlds ahead of China's 14.
Freedom House is a US charity though. Looking at any other report will still show China much lower in the ranking but the US also not really looking as good as the land of freedom might see itself.
How about a look at Reporters without borders, which ranks press freedom:
US #48 (behind Botswana, Child and Romania)
China #177 (of 180, so only ahead of Eritrea, NK and Turkmenistan)
After 350 years of economic and social terrorism, I would say it's fair to say most of the AA people in jail did not have a fair legal process, they couldn't afford it even if you ignore the combination of systemic/overt racism.
We have to remember there are two justice systems in this country and re-introducing slavery through the prison industrial complex was something we deliberately did without good reason.... not in response to dangerous extremism like in China.
For perspective, you can critique the US government(s) (state/federal) and say that this is a bad thing, and you won't disappear. I doubt you can critique the Chinese government about the re-education camps.
Here's a major presidential candidate on the topic:
> These camps are reportedly operated outside of the legal system; many Uyghurs have been interned without trial and no charges have been levied against them.
This is a fundamental difference (and yes, America has detained people indefinitely without trial, but I would condemn that _too_, and they are a small minority of prisoners).
Furthermore, there are ~2.3 million _people_ in prison, of which 40% are black (39% white, 19% Hispanic).
