Significant Other’s family have mainland father, Taiwanese mother. (It was an arranged marriage.) Children all think of themselves as mainlanders, and not as mixed-ethnicity. During the election they were parroting whatever the other KMT people were saying, including the conspiracy theories, and insisting that I “didn’t understand” while they did.
About China (and I think this is typical of mainlanders) they see themselves as “Chinese,” but are in absolutely NO hurry to reunify. Certainly not under communism, and maybe not even after unless there was money in it (which seems doubtful). They’re practical people, and want to keep what they’ve got.
As for high/low culture, the father got drafted as a youth, the mother is illiterate. You could call them BOTH “bumpkins” if you were so inclined–they do go out to garden wearing those wooden farmers’ hats. But they worked hard together and made a lot of sacrifices over the years so their five kids could all go to university.
An interesting question is, what about the younger “mainlanders”? Will they even be interested in politics at all? (A lot of them would rather “vote with their feet,” which is fine.) Or am I basing my perceptions on too limited a slice of the population?
