Talk to some Chinese. Or, even worse, people from Hong Kong. The behavior of the Chinese state is disgusting. Even at a local level constant abuses are the norm, in big cities and small. People are "disappeared". Not 1, not a few per year, but hundreds of thousands per year.
Did you see the size of the Xinjang internment camps they built then tripled in size ? But these disappearances are happening all over China, not just Tibet, Xinjang and Hong Kong. All those regions, by the way, have populations in the tens to hundreds of millions of people.
And there's the steady trickle of stories by people that somehow make it back out of those camps, talking of torture, executions, slave labour, starvation.
Let's just stop mincing words here. China is executing a holocaust on it's own people. That's the truth.
