Forcible displacement of populations and remvoing children from their parents and culture is considered genocide. For an example of the latter, see Putin's recent indictment by the ICC.
The word "genocide" means mass murder of an entire ethnic group. You're using the word because you know that that's how people interpret it, and you want the shock value.
Exactly as I said, when pressed, you try to redefine the word to mean something completely different.
By the way, even the far lesser claims you're making are incorrect. The Uyghur population in Xinjiang continues to grow, life expectancy is increasing, the language not only continues to be spoken but even continues to be the primary language used to teach Uyghur children in school. There is political repression, targeted particularly at what China regards as separatism and religious extremism, but the "genocide" accusation is pure bad faith.
The people claiming it's a "genocide" don't even claim that anyone is being killed. If you actually press them, they try to redefine the word "genocide" to mean something completely different.
Words have meaning, and a word as important as "genocide" should not be thrown around in bad faith as a polemical tool.
