Better question: what’s the beef?
The beef for me is that China oppresses more then just Tibetans, Uyghurs, Hong Kongers, Taiwanese, and and whatnot. But it's more than just them. Many people don’t know of the many Mongols that live in Inner Mongolia who only wish to be part of Mongolia again, but China won't allow it and only treads on them.
That's my beef.
