We have thousands of years of examples of two “blood kin” groups attacking each other. In addition to this is the fact that not all peoples with roots in present day PRC are Chinese. Tibet is a region of PRC that is not Chinese, for example.
Party leadership is Han Chinese and everyone else is a subject of the Party-owned and operated State within PRC jurisdiction.
Yes. I was referring to the comment about “blood kin”. Not all peoples native to present day PRC borders are “blood kin” and certainly not all people from Taiwan are Han.
