They also didn't refute anything the parent said. "Dubious claims from biased sources" isn't denying that Uighur exploitation happens, it's a strawman that diverts the criticism to the media. Same goes for the CIA/NSA comment and incarceration statistics - they seem to be under the impression that other countries taking nuanced action excuses nuclear-option behavior from a one-party state.

Suffice to say that if the United States is deserving of criticism, then China's actions are due double the scrutiny. As an American citizen, I take no issue holding both countries accountable.
