Calling Taiwanese people Chinese is a mega-cope. I mean it's okay to mention that rhetorically, but if you
actually think like that deep inside, you have some real bias.
That's how Russia miscalculated in Ukraine. Thinking "everything will be right", "they will realize over time", "we are the same people" and other irrational self-delusions and copes.
It's okay to acknowledge history, but it's really dumb to keep living in the past. Ethnicity itself is a social construct, so why it wouldn't be changed over time especially if deliberately targeted by a masterful psy-op?
There is very little chance they will ever return to China outside of real
physical/tangible action and establishment of PRC control there
first.
