Open it in Twitter my friend.
I watched the video.
While he doesn't call for ethnic cleansing and claims that he has the support of many Uighur students, he is calling for Han Chinese to guard these provinces (Xinjiang and Tibet) and make sure they are not lost. He also jokes that Xinjiang is surrounded by countries that aren't good, all of the stans basically.
I mean he is a nationalist jerk, but honestly I hear way more inflammatory stuff every day in the US media so maybe I am desensitized.
