I just looked into the history of Taiwan and China and it looks to me like the previous government of China lost a civil war and then retreated to Taiwan.
Really puts into perspective all the useful idiots saying "Taiwan is China." They're literally following the same logic as "the South will rise again."
Propaganda is real. Indoctrination is real. Tribalism is real. If you feel you're immune to them, then you're probably the most susceptible.
