>You and the previous poster seem to ignore that the punishment is just (to the extent that the criminal justice system is capable of justice).
By your logic, the Uighurs are experiencing "just" punishment under the laws of the People's Republic of China.
Since the Uighurs have committed "crimes" (as defined by the government under which they live) against the state, they are subject to whatever punishment is prescribed by the law.
This is, of course, ridiculous on its face. And is just as ridiculous anywhere else.
There are valid reasons to separate some folks from the rest of society (think John Wayne Gacy, Jeffrey Dahmer, Ted Bundy, etc.), as they've shown themselves to be unable/unwilling to respect the rights of others within that society.
Incarceration as a tool of punishment, while widely used, often poses more risk of harming society than any benefit from "punishing" offenders.
It's a complex issue, and simplifying it to "Law and order! Lock 'em up!" is reductive and often detrimental to the societies it's supposed to improve.
