It is somewhat ironic, given the context, that xtian’s dissent from the popular narrative is so vociferously countered, and without any recourse to facts.
However, at the same time, it could not be more blatant that the Ughyurs face persecution. However sympathetic one is towards China, nobody should forget that it is an authoritarian state, with few political or civil rights, and sometimes that can have serious consequences for groups targeted by the state.
China has historically had a great record in regards to minorities - far better than many countries in the west - but it's obvious that a combination of the war on terror and a rising form of Han nationalism has caused a drastic change in policy, first starting with fairly ordinary persecution (veil bans, etc) then escalating to acts that would be basically illegal in non-authoritarian states.
Denying this neither helps China nor anybody else. It is possible to find western behaviour cynical, and to have serious concerns about the path China is walking.
