The TW youth have so far been shielded from their delusional beliefs due to TW's economic prosperity. However, this prosperity is being slowly eroded.
When you keep lying to yourself, eventually reality is going to bite you on the ass.
When TW's economy collapses from mismanagement, all the deep greens will suddenly remember that they are also Chinese.
Honestly, one main reason for the rise of DPP is the poor economic prospects for the young people in Taiwan, and this has been going on for a decade now. Young people come out of university with a degree that often does not get used, and many have to resort to making bubble tea or selling cheap clothing in flea markets. Meanwhile, property prices keep going up, and there is no way they can afford to own their own homes. Taiwan is prosperous, yes, but the prosperity is uneven and unequal across generations. DPP promised to bring social equality and reduce the priviledges of the business community, many of which has mainland ties.
In fact, the disdain of mainland China can be seen as an evolution of the disdain of the wealthy business community among the socially and economically dejected youth, and certain disadvantaged classes of society in general. Mainland China is the backer of the businesses that, in their view, is not bringing about prosperity in a way that benefits them. So, one can argue that, the more Tsai's policies hurt the business community, the more she is actually feeding red meat to her core constituency. Her core voters are not that concerned by economic issues, I guess so long as living standards do not fall to India or some poor African state.
In this vein, I think any moves aimed by the mainland aimed at hurting Taiwan's business community, for example by restricting the flow of imports or tourism services, is counterproductive. These moves hurt the segments of society that tends to support more mainland integration, and is ignored or even savoured by the radical elements.
As an aside, the N word is not appropriate to describe Taiwan. It is not like that.
