Perhaps a million Uyghurs in Xinjiang, China have been put in "reeducation camps". Inmates learn to say how great it is to be in a reeducation camp.

We have to acknowledge that Islamist extremism has had an influence among the Uyghurs, and some became terrorists. At the same time, Uyghurs resented having millions of Han Chinese moving into their home and outnumbering them. China did the same thing in Tibet, and is now crushing Tibetan culture.

Indonesia has done something similar, moving millions of Javanese colonists into the areas inhabited by less dense populations of different ethnic groups.
