Chinese nationalism probably should be banned in China (but not the US) for the same reason that white nationalism should be banned in the US: the racial designations "white" and "black" are completely arbitrary terms, not grounded in any scientific fact, and are social constructs based around an in-group (whites) wielding political, economic, and cultural power over an out-group (blacks). "Irish" is an ethnicity. "Lithuanian" is an ethnicity. "White", on other hand, is most definitely not an ethnicity, and identifying as such implicitly supports the present racist status quo, because the white in-group already wields overwhelming power in American society[1]. White nationalism asserts that only those Americans who identify as white are "real Americans", and therefore explicitly advocates for the exercise of white cultural and political dominance at the expense of all other out-groups. And at its most extreme, it advocates genocide as a means of accomplishing its vision.
