colonies

If you think China colonized Xinjiang, well… yeah, they did. But that was 22 centuries ago, a millennium before the [people now known as] Uyghurs had even arrived there. The demographics and ruling empires unsurprisingly changed a few times in the ensuing millennia, but since the Qing dynasty committed the Dzungar genocide there (from 1755–1758, with help of several peoples including Han and Uyghur) it has mostly remained a part of China.

The ancient history is interesting, but more recent events (eg Al-Qaeda-affiliated groups the US was funding there) are more relevant to the present situation.

I did watch the first three minutes. Everything he shows is true, everything he explains as interpretation is just full of shit.

What specifically is he full of shit about? I recommend watching more than three minutes of it.
