You are using the people claiming there is a genocide as the source for the claim.

That's typically how investigations work.... There's an accusation, and then an investigation to find evidence that supports the claim. They aren't using people as a source for the claim, they're using the evidence the people gathered.

You on the other hand seem to be focused on who gathered the information instead of what they gathered.

Welcomes** the outcomes of the visit conducted by the General Secretariat's delegation upon invitation from the People's Republic of China; commends the efforts of the People's Republic of China in providing care to its Muslim citizens; and looks forward to further cooperation between the OIC and the People's Republic of China.

This is anecdotal evidence from a political organization that has a well established history of ignoring the plight of specific Islamic ethnic minorities, including the Kurds in Syria and Turkey, the Ahwaz in Iran, the Hazaras in Afghanistan, the 'Al-Akhdam' in Yemen, and the Berbers in Algeria.

Over 50+ UN member states (mostly Muslim-majority nations)

Again, anecdotal evidence which does not detail the accusations, nor how their experience contradicts that accusation.

The World Bank sent a team to investigate in 2019 and found that, "The review did not substantiate the allegations."

Using this as "evidence" is just academically dishonest. The "team" was a single bank manager, and the "investigation's" scope was solely to insure that a 50m dollar loan for 3 different schools were not being used to commit crimes against humanity.

The bank claimed that the specific schools they investigated did not substantiate the allegations, however they found enough to decide they wanted to minimize the project.

"In light of the risks associated with the partner schools, which are widely dispersed and difficult to monitor, the scope and footprint of the project is being reduced. Specifically, the project component that involves the partner schools in Xinjiang is being closed."

China’s mass imprisonment and forced labor of ethnic Uighurs in Xinjiang amounts to crimes against humanity—but there was insufficient evidence to prove genocide

I think you are forgetting the accusations of the population control of an ethnic minority. "The 1948 Convention on the Prevention and Punishment of the Crime of Genocide, which lists birth prevention targeting an ethnic group as one act that could qualify as genocide."

Comparative Analysis: The War on Terror

Again, a logical fallacy. Just because America has participated in genocide does not mean that China cannot also participate in genocide or crimes against humanity.

Who is driving the Uyghur genocide narrative

Another logical fallacy.... You are attacking the man, not the evidence or argument.

He relies heavily on limited and questionable data sources, particularly from anonymous and unverified Uyghur sources, coming up with estimates based on assumptions which are not supported by concrete evidence.

The vast majority of the evidence he's gathered for his peer reviewed study are gathered directly from public data released by the Chinese government. There have also been some data from a leaked cable, which have been validated by multiple investigative bodies of journalists across the world.

As materialists, we should always look first to the economic base for insight into issues occurring in the superstructure. The Belt and Road Initiative (BRI) is a massive Chinese infrastructure development project that aims to build economic corridors, ports, highways, railways, and other infrastructure projects across Asia, Africa, Europe, and the Middle East. Xinjiang is a key region for this project.

This is a biased interpretation of materialism. A similarly biased claim based on materialism would be that the Belt and Roads initiative motivated china to ethnically cleanse a region vital to the initiative.

On a personal note, I don't think the lable of genocide is really important. What is important is that an ethnic minority is being abused by a State. And while there is a lot of misinformation and politicing surrounding the topic, there's still an alarming amount of data that suggest China is forcibly assimilating an ethnic minority group.
