You realize that there is no blanket action and 95% of Muslims and Uyghurs aren't arrested? Don't just listen to propaganda. Millions of Uyghurs are living regular lives. The current top actress in China is a Uyghur, an Uyghur just won the Rap of China, the situation is nowhere close to Japanese internment. The people targeted are the ones who had suspected contact with Wahhabist extremists. The process is non-transparent and probably incompetently executed but that's a function of China's immature and authoritarian justice system.
