Nearly a million Tibetan children live in state-run residential schools on the Tibetan plateau. Chinese authorities subject these children to a highly politicized curriculum designed to strip them of their mother tongue, sever their ties to their religion and culture, and methodically replace their Tibetan identity with a Chinese one. Children as young as four have been separated from their parents and enrolled in boarding kindergartens under a recruitment strategy based largely on coercion.
"nearly a million tibetan children live in state-run residential schools" - so like every else in the world where public school is normal?
"highly politized curriculum" = teaches about the society they currently live in
"Strip them of their mother tongue" = teach them Chinese because they live in china
"Replace their tibetan identity with a Chinese one" = assimilate them into the culture of the country they are apart of. This complaint is fair and I'd criticize any country that actively suppresses a native culture but the language used here is quite dramatic and misleading.
