It's a hot take because while you are right, it's something that all countries do. It's just not necessarily the government that does it. Just look at the culture wars in the US. China's biggest difference is it's controlled by the government. But it also has nothing to do with Xinjiang. They do it to everyone, Hans Chinese inclusive. Technically that's what the great leap forward was. First forcing the Hans Chinese people to assimilate to the government's idea of a unified country. It worked, so they're pushing it everywhere.
Also, it's important to note that the only violent enforcement of this was on the Hans Chinese. This was Tian an men. After that they've gotten really good at subversion. There was only one suspicious killing in the HK riots for example. For as large a protest as it was, it was largely nonviolent. Compare that with BLM in the States.
