There are no re-education camps in Israel that Israel declines? And on the other hand, in Israel, there is Gaza where they have no real authority and which is actively antagonistic against them?
Sure, Israel is occupying power on West Bank and preventing Gaza from getting supplies, but, it's on a different scale than what is happening in China?
I don't know enough to say how much power does Palestinian Authority actually have in West Bank; but it is much more self-governing anyway than anything they have in Xinjiang with Communist Party.
"No one is talking about X" is pretty much only ever said about political situations which generate enormous (disproportionate) amounts of discussion.
