Taiwan does have some cool history when it comes to resisting colonization efforts, like the Hakka shooting up the Japanese forces when they first landed in 1898 (and then getting murdered in retaliation unfortunately) (also the Hakka were themselves settlers or descendants of settlers, of course. "The history is complicated")

and the indigenous Seediq chopping off heads of Japanese occupation forces a couple of decades later (and then getting murdered in retaliation unfortunately)

but for some reason I don't expect that guy to know any of that. I may be wrong but I'm going to assume someone calling themselves Chicagofire, complaining about "sweeping generalization of americans" and using terms like "PRC" and "Formosa" is, in fact, a USian, and like most USians, know nothing of world history
