Taiwan is a democracy and a majority of Taiwanese want independence but argue for keeping the status quo in order to avoid a war (both the KMT and the DDP - their disagreement is more technical than that). Some wanted Taiwan to declare it in the 90s to force the hand of the USA and win a decisive war but this position seems more precarious nowadays.
We both know, that you do not agree that the moon is made of cheese, in this situation. I have just made words come out of your mouth, to something that you do not agree with.
To say that they "agree" is just a silly word game, that does not reflect the truth of the matter, and instead is playing into propaganda that denies the reality that Taiwan is already a country, and is already independent of china, and that Taiwan is not interesting in being taken over, or taking over china.
