yes there can be a debate about specifics but nothing we say will not make that genocide just like what's going on in China.
What is going on in China is a form of genocide if the allegations made by e.g. Amnesty are true. I think people ought to suspend judgment about the truth of the accusations because human rights NGOs are staffed by people rather than infallible truthtelling robots, and there are incentives and pressures on people who work at these organizations to support certain narratives in order to both maintain the relevance of their organizations (attention paid by mainstream news outlets) and secure funding.
For example, Human Rights Watch (the whole thread these tweets are a part of is well worth the read)
All credit to them for finally declaring Israel an apartheid state some number of decades late, but they are absolutely not above criticism. Tellingly,
none of the above was ever a big scandal. The media treats such things with a collective shrug of its shoulders; criticism is marginalized not by some conspiracy to keep the truth hidden but by simple failure to spend any time whatsoever examining it in popular publications: just move on to the next story. Perhaps it helps that such failures are ubiquitous. I've read that Putin's propaganda machine aims to make everything uncertain; if so, he probably learned that technique from us.
People are capable of misrepresenting situations in order to further the designs of US imperialism, and just like the promise of some lucrative consultancy after a period in government, the same sort of opportunities exist for people who work at human rights NGOs and "promote human rights" in the desired ways. There are reasons for the United States (or the ruling class that it serves) and its media vehicles to promote hostility toward China that have absolutely nothing to do with human rights but which nonetheless would not stand well on their own in promoting the desired hostility. And so we have a situation where there is ample incentive for allegations made against China to be published and popularized and for critiques of those allegations to be suppressed or ignored by a relatively concentrated mainstream media. A degree of suspicion toward accusations about Chinese violation of human rights is therefore justified no matter what is actually going on in Xinjiang; just because propaganda isn't as nakedly racist and cartoonish as that employed in the 1940s does not mean that it isn't propaganda.
Representations of China as a Han supremacist state are, of course, very convenient for people who want to muddy the waters or ignore the white supremacy of the United States. The accusation of genocide against Uyghur Muslims is very convenient for Zionists who want people outside of Israel to ignore the ethnic cleansing of Palestine ("what about these other Muslims? Ignore the thing you can influence, what about that thing that you can't?!"). Getting the political left on board with (or at least less vocally opposed to) anti-Chinese actions requires more than just "well, global finance capital can't control them as easily as it can a place like Colombia"; the prospect of human rights abuse is exactly what is needed. Such can be weaponized just like fabricated security threats were in the case of the invasion of Iraq. Say that "Iraq WMD is different" all you like, but people were fired and essentially (if not formally) blacklisted from appearing on mainstream news for being
on the right side of that, while those who were wrong in the correct way of uncritically parroting and accepting the premises for war (whether or not they personally endorsed the war itself) mostly advanced and prospered: a lesson which no doubt endured, as the media's complicity in the Iraq invasion has never been reckoned with in any sufficient way.
The United States is currently experiencing hegemonic decline, and the last time that sort of thing happened there was a world war in which Germany, Italy, and Japan challenged the supremacy of the British Empire and the British Empire was ultimately supplanted by its ally (the United States) or allies (the US and Soviet Union) depending on how you look at it. The Chinese are the strongest rival to the United States and have a much larger population and more impressive economic growth, so to avoid being supplanted by China the United States would likely have to confront it directly at some point and the earlier the better from its point of view. The biggest problem with that, of course, is nuclear weapons: I'm not confident that the ruling class of the United States (or to be more precise the apparatus it has created to secure its power) would choose to relinquish world domination rather than suicide the world in thermonuclear warfare. In any case, the accusations against China may very well be true, but it's all a little too perfect in my opinion to just uncritically accept.
I don't think there is any blame in skepticism toward a system of propaganda that produces people like the woman on the right in the following clip.
