I would say that suicide is not patriotic to anyone.

But you have nothing to say to about America not allowing integration with China without launching a world war? Curious.

The PRC has never owned Taiwan

What a fucked up imperialist framing. The PRC doesn't own China, it is the current government of the sovereign nation of China which has included Taiwan for a very long time and still includes Taiwan. You don't say that the Democrats don't own Alabama, but you apply an idiosyncratic standard to argue that the US is justified in turning Taiwan into it's military proxy and threatening to send millions to their death over reintegration of a territory that is quite literally by all standards part of the same nation as the mainland.

Also, it doesn't matter about the ethnicity of the population because, at the end of the day, they don't want to be part of China.

You are talking about people who suffered under the White Terror for 40 years, which included torture and murder of anyone who disagrees with the KMT. The individual beliefs of the residents is a direct result not only of the indoctrination from that White Terror but from the heavy indoctrination by European propaganda for many many decades.

What matters is that there is no way from Taiwan to be independent. It will either be part of the imperial bloc and therefore a military threat to China and a base for Western imperial power projection and containment, or it will be administered as a province of China and the Europeans will be kicked out of their foot hold. This is why the conflict exists, not because the people in Taiwan care one way or the other, but because independent Taiwan is a strategic position for the European imperial order. China will integrate it because it is required for Chinese national security, which serves not merely the people of the mainland but also the people of the island. It would be tragic for the US to turn Taiwan into another meat grinder in its bid to use proxies to maintain its global oppression.
