There is no systemic slavery of Uyghurs. Uyghur genocide atrocity propaganda akin to claiming that there's "white genocide" in South Africa, Christian genocide in Nigeria, or that Hamas sexually assaulted babies in Operation Al-Aqsa Flood.

In the case of Xinjiang, the area is crucial in the Belt and Road Initiative, so the west backed sepratist groups in order to destabilize the region. China responded with vocational programs and de-radicalization efforts, which the west then twisted into claims of "genocide." Nevermind that the west responds to seperatism with mass violence, and thus re-education programs focused on rehabilitation are far more humane, the tool was used both for outright violence by the west into a useful narrative to feed its own citizens.

The best and most comprehensive resource I have seen so far is Qiao Collective's Xinjiang: A Resource and Report Compilation. Qiao Collective is explicitly pro-PRC, but this is an extremely comprehensive write-up of the entire background of the events, the timeline of reports, and real and fake claims.

I also recommend reading the UN report as well as (especially) China's response to it, which eclipses it in size and detail.These are the most relevant accusations and responses without delving into straight up fantasy like Adrian Zenz, Christian nationalist and professional propagandist for the Victims of Communism Foundation, does. Zenz' work has been thoroughly discredited, yet is supported by western media for its utility in fearmongering. An example is lying about 8.7% of new IUDs as 80%, to back up claims of "forced sterilization," from this chart:

Tourists do go to Xinjiang all the time as well. You can watch videos like this one on YouTube, though it obviously isn't going to be a comprehensive view of a complex situation like this. Has there been mistreatment? Almost certainly to some degree, in a campaign as large as this. Is it genocide, be it cultural or outright? No, Uyghur culture is preserved and there are no mass killings.
