A nice Taiwan political spectrum map I came across, according to polling the left (less separatism) side only has 12% of public support, while the right (more separatism) side has 88% public support. Without a war or major bloodshed, I don't see how PRC can rule over Taiwan without much resistance.
Suppose you "remove" the rightmost 20% population of the population, then shift everyone to the left one stage, you would barely arrive at a Hong Kong level of political spectrum.
