The myth of american moral superiority had been dead for a while. Why would china be any more evil than the US, which has waged far more colonialist wars and killed far more foreign lives in recent times (look at the news today for inspiration)
There’s absolutely no consensus that the legal definition is met, in contrast with another ongoing situation which enjoys wide recognition.
It feels that this is more a geopolitical cudgel, pulled out when the discourse against the US becomes negative. But given the events in the last years, this seems like a lost cause even in the West, never-mind the rest of the world.
But that's beside my point. It's too late to edit my post, so pretend I used the word "culling" instead of "genocide." How does one weigh a Uyghur culling against a South American regime change? What's the exchange rate?
