No, it would be "cultural genocide", which bluntly is empty label - there's a reason no international framework exits for something prosaic like enforcing common language and culture on minorities - because it's nation building 101. And regardless that's not even what PRC did, they didn't turn Uyghurs into non Muslims, they Sinicized them back to traditional Uyghur + state Islam and excised strains of extremist Wahhabism which was recent import. You know how western minorities mostly speak the dominant language, aka melting pot, that's what PRC minority policy is moving towards, away from soviet autonomous multicultural oblast model which was too hands off leading to minorities getting to restive/handsy with terrorism/separatism.

German jews btw overwhelmingly spoke German, were deeply assimilated, patriotic of course. XJ would be like if German Jews who spoke only Yiddish and stuck in their minority enclaves, carried out 100s of terrorist attacks, got reeducated to speak both German, and Yiddish, reform religion to be less extremist, and doing it in <10 years / single generation. Not only would it have not been genocide, it would have been exemplar model to emulate for domestic serenity. Which is broadly what XJ securitization was, the most successful deradicalization and integration program in human history. Not unique to human history... again integration = nation building 101 stuff, it was just technologic mediated speedrun, in that sense parallels Germans.
