Sorry but it just isn't. INDIVIDUAL things the CCP does today dwarf the sum total of the atrocities the US committed over it's entire lifetime. The situation in Xinjang has more victims yearly than every event in the US since it's founding, and it's not even close to the only mass-atrocity the CCP is engaged in. Tibet. Mongolia. Chinese religious movements.
Ah you're a communist idealist who "won't go into details" (and you'll probably refuse to discuss why almost every attempt at communism ended in a massacring dictatorship ...)
The US supported genocide in Gaza alone is much worse than anything done in Xinjiang. The genocide of native Americans, the bloody coups and corporate abuse in south America, the wars of the middle east with their millions of victims, the war crimes in Vietnam, the bombing of Japan and who knows how many more horrors that the US has been involved in. Do you honestly believe those things combined have less victims than Xinjiang?
Not that your other claims aren't equally ridiculous, but sorry, no. Pretty much everything, in China or elsewhere, is worse than Gaza.
Gaza, claimed victims (hamas numbers, rounded up): 65'000 dead. (note that these numbers are ridiculous: for example, did you know, Israel did not kill a single hamas member? Zero. Not a single one)
Gaza, claimed victims, IDF numbers: 13'000 dead (a little under half claimed to be hamas members. >80% are fighting age men)
(and let's not forget the other difference: in the victims of Hamas, >85% are civilians. And that's assuming that everyone, on duty or on holiday, working even indirectly for the military counts as a soldier, including locksmiths and cleaning staff, otherwise it's easily over 90%)
So let's say it's somewhere between those two numbers. But every conflict in the area is bigger than the biggest numbers in Gaza, easily.
Syria, right next door, death toll: 656'000 dead.
Sudan, not that far from Gaza, with hamas' parent organisation the perpetrators: 300'000 dead.
Lebanon (note: conflict started by the PA, against Christians), death toll: at least 150'000 dead.
IS/Daesh (note: conflict started by Palestinians), death toll: 306'000.
Xinjang: 1.2 million imprisoned, 10% dead, per year, according to UN. Obviously that would make it more than double the claimed Gaza death toll PER YEAR (so that would make it 4x as big during the Gaza conflict, except it's been going on for far longer than the Gaza war).
