Thank you for the explanation of your position here, it is the best take for this being an overreach on China's part I've seen.

However, keep in mind that examples of ethnic oppression have also been wildly exaggerated by those with ill intentions. Westerners have a tendency to immediately draw lines to their own nations' history of genocides and violently reject anything that even resembles treading that path. If China doesn't intend to carry it out to such an extent, that characterization would give the wrong conclusion.
