To be fair, DPP is now trying western liberal ideology to try to bring a sense of togetherness. Gay marriage recognition, virtue signalling through appointment of trans minister and aboriginal officials (we swear we are sorry!), etc.
You mention CCP, but actually it was KMT under Sun Yat Sen who promoted ethnic harmony. KMT had many minority supporters and once they took power in Taiwan quickly recruited the aboriginal population.
Will DPP be successful? Remains to be seen as they have to try to shed decades of Japanese inspired ethnic superiority theory (See South Korea for what happens when that theory becomes too powerful)
Togetherness? More like sucking up to the US liberal. And yes, people who are gay in Taiwan are going to be making a difference when confronted by the PLA. LOL
It’s not ethnic harmony. The official name for Sun’s idea was “5 ethnics harmonic republicanism”, more specifically the Hans, the Manchus, the Huis, the Mongols and the Tibetans.
The “Many minority supporters” is certainly an over exaggerated statement, not saying that they do not support the ROC. But that they are only a handful of trophy ones left. Most of them were wiped out over the course of two century of infighting, Japanese genocide, conflicts with Qing Dynasty and Han Chinese settlers and intermarriage with Han Chinese settlers long before the ROC relocation.
As for the DPP, their successful or not is irrelevant for mainland. They are in the mainland’s mind 10 times worse than the “counterrevolutionary traitors” of right-KMT.
