The KMT doesn't represent Taiwan. Tsai, obviously the former president, has already said that Taiwan is already independent and doesn't need to "declare independence". China's position is 100% LARP. Their claim is that they already own Taiwan, which makes no sense at all.

There are basically ZERO pundits anywhere that know the history of Taiwan. They either parrot same NAFO-type propaganda or CPC propaganda -- which is basically that Taiwan is an "inalienable part of China", which is simply historically false. Throughout most of Chinese history none of the leaders gave two shits about the island of Taiwan until it became part of an important trade route. THEN the Qing dynasty started to administer very very small parts of it. They were later forced to give up their rule on those parts of Taiwan to imperial Japan for many reasons (yes, imperial Japan is bad). Afterwards, there still wasn't much of a concern for taking Taiwan, either from the CPC nor the KMT. It only started happening after KMT lost their war and started claiming Taiwan was theirs and planning their escape plan. Shortly afterwards, the CPC said Taiwan was there's as well.

In the bigger picture, aboriginal Taiwanese have arrived at Taiwan in various periods, starting around 6000 years ago. The vast majority of "Chinese" that came to Taiwan came starting around the 1600's due to the Dutch East Indian company encouraging immigration from China and later on the Qing dynasty encouraged immigration as well (1800's). CPC propaganda makes it seem like "Chinese" presence in Taiwan all came from the KMT fleeing to Taiwan or something. The KMT and all of their descendants only make up less than ONE FIFTH of the population of Taiwan.

Anyway I skipped over a lot of history including Dutch atrocities in Taiwan, a Ming loyalist dispelling the Dutch, and the Spanish colonization of (small parts) of Taiwan https://en.wikipedia.org/wiki/Dutch_Formosa
Taiwanese identity is also very important and unlike what the CPC says, it's not about being "anti-Chinese" or "not Chinese", which makes no sense.

Also, what does being loyal to "China" actually mean? The Ming dynasty had conflicts with the Qing dynasty, which one was more Chinese? Is the CPC responsible for everything bad previous dynasties did? Should the CPC take responsibility for KMT atrocities?? If no, why not? Do they own all the land that previous dynasties have owned? Does the CPC own all land that Chinese people live on? (Chinese nationalists actually use the ethnostate argument as a reason as to why the CPC should own Taiwan).

Sure
