I agree they should support Taiwan and most do, but I don’t believe their unwillingness is partisan or knee jerk contrarian, They disagree with the foreign policy /economic policy or military strategies they’re being asked to get behind.
Also some pretty reasonable mistrust of the appointments themselves. Asking progressives to get behind neoconservative war hawks in the name of democracy is a tough sell, and the same crew called for a war that didn’t go all that well the last time around… theres some reason to be skeptical.
There was a big rally for legalizing gay marriage a while back in Taipei and this was during the short lived honeymoon between Taiwan and Trump with the phone call stuff. One aquaintance of mine was wearing a MAGA red hat, bashing liberals and PC culture, and then at the same time there to support a legal appeal for the rights of gays to marry. Politics make strange bedfellows.
