I think there’s a pretty notable difference between what your grandmother went through and China’s policies in Xinjiang. The Canadian cultural erasure program was a blanket program to try and erase the culture of all indigenous people. In Xinjiang, the vast majority of Uyghurs haven’t been affected by the anti-extremist program. It’s a much more limited scope and they mostly target older, chronically underemployed economically vulnerable people to put into a vocational program so they can get employment and get deradicalized from the ETIM ideology. The whole point of the program was to protect all the other people in Xinjiang province from an extremist group, not to integrate them into Han Chinese culture.

I’ll leave you with The Xinjiang Atrocity Propaganda Blitz as further reading, but this focuses more on the semiotics and ideology behind this narrative than the actual facts. There used to be a Google Doc called “Notes on China Uighur Controversies” that I read some years ago that explained the full situation with the ETIM and CIA backing of the ETIM very well, sadly it seems it’s now down and I don’t remember what their sources were (I think many of them were Chinese sources which I can’t read anyway).
