This repression is egregious, as it is an on-going VIOLATION of the UN’s Charter (Constitution) but the PRC sits at its permanent seat on the UN Security Council and on multiple committees dealing with ‘Human Rights’! Still this is a sad refrain with history as the Soviet Union and even India were notorious for much the same criticisms while oppressing their own minorities. India has become much less vocal on this following the collapse of the “Non-Aligned Movement” in the 1980s.
The Han are probably the most racist people on the planet. Ask any of them at random and they will gladly boast of it.
