………genocides? That requires a fuckassload of elaboration. To my knowledge, which is an unfortunate amount, the modern Chinese state hasn’t engaged in anything which could be labled a genocide. The US state, however, is currently sanctioning (a lighter form but still a form/method of genocide) multiple nations for no reasons they can explain properly. Cuba being chief among them. Support of Israel and Saudi Arabia (and others) is also supporting genocide (of the Palestinians and the Yemenis respectively).
China on the other hand, in the last couple decades, has been “accused” of “cultural genocide” an important word to note is cultural… they then made changes to the tactics of imprisoning Uyghurs, which is debatable how much/how bad it was to begin with, and basically all the stuff anyone could complain about in that respect has either been disproven or corrected. The US has absolutely no moral ground to stand on here though considering the historic and ongoing treatment of black and indigenous peoples in the US which are treated insanely far worse than anything ever accused of China in regards to the Uyghurs, which again, they stopped doing the spying and arresting/harassment shit once people complained. That’s kind of the difference between the US and China… China usually stops doing shitty shit when people call them out on it (if it was ever even shitty or real to begin with- many stories the US state dept tries to push (remember that balloon thing? Lmao) are straight up lies based on Sinophobia).
It’s incredibly odd to criticize China, admit western nations have and are fucking you harder, but then still rail against China so hard. My advice: change what you can change. That means change the laws and the actions of the western government you live under. Once that is done THEN you can perhaps criticize foreign governments. Further advice: do so on things they’ve actually done, not made up or super exaggerated projections from the western state departments/media (same thing).
