That the majority of Taiwanese want to become Chinese?
That it doesn’t matter what the Taiwan population wants because China has the right to claim it?
I would say that the majority of the people of China are much like the majority of the people of any land, they don't directly care about the issue. Someone on the other side of the country in Karamay probably doesn't even think about Taiwan for most of their days.
However, according to the government of China, Taiwan is an island occupied by a rogue government, the last remnants of the losing side of a Civil War. That island is part of China.
The people of Taiwan have different opinions. Three major ones last I looked. There's the opinion of the natives who think Taiwan should be its own country, independent of any other country's influence. Control of the area has alternated between China and Japan. With China getting control back in 1945 after WWII.
Then there's the people who believe that the ROC should be reinstated on the mainland.
And finally, some people who think they should just become members of the PRC and get all over with.
I mean, it's not an opinion, it's a fact of how things went.
Personally, the PRC has been the de facto government of China for long enough that the ROC loyalists in Taiwan should accept that the war is lost.
The big question is to what to do about the island of Taiwan. After the end of WWII, it was surrendered to China. If the Chinese Civil War hadn't resumed, Taiwan would be part of China. But the ROC occupies that territory. And they were the China it was surrendered to. But if we accept that the PRC is China, then we do need to consider their position that by being China, they should be all of China. But sometimes, the resolution of a Civil War is that a nation fractures into multiple.
But there isn't a big enough faction on either side of the strait to accept any solution. And even if Taiwan would accept a two state solution, getting China to accept that is a big ask. I think if China ever accepts a two state solution, Taiwan jumps on it. I think even the restorationists in Taiwan would accept that as a way to end the tension.
