Your point is a good one actually, and it's why I didn't mention anything about genocide in Xinjiang. It's a grotesque political atrocity of social repression and culture eradication, but as far as any sources I've looked at go, the Chinese state isn't literally killing the Uyghers en masse as an ethnic or religious group.

Nonetheless, the deaths of civilians in the Gaza Strip also aren't a genocide. They could be defined as a war crime, or if you want to be really generous to Israel, as unfair collateral damage (a phrase I mostly detest in this context) but the Israeli state isn't deliberately targeting the Strip's ethnic Palestinian population for eradication.
