Furthermore, the Chinese sense of history is much longer. There are many examples in Chinese history in which some territory splitted off and then reunified later. So things like "the configuration won't be stable" wouldn't be Chinese thinking. To the Chinese, splitting off is the unstable configuration.
Given how the current Taiwan situation came to be, many Chinese view the Taiwan government as relatives with whom they've had a fight, and whom — after losing — bunkered down in the basement. The basement is still part of the house. They're still part of the family, so let's not be too cruel to them and seek peace. But if they no longer claim to be part of the family, then kick them out.
Don't they all consider themselves Han people? How do they configure their identity? Their ethnic and historical ties do not appear to be severable.
Some of us have difficulties in understanding the mindset: if some population wants one system, and is unavailable to be part of a different system (they would have moved, would not they), how do those "reunification supporters" on the other side believe, psychologically, that a system change is imaginable? They believe that coercion can be an effective solution? That "the others will adapt"? If so, that the new configuration will be stable (like a model of energy states)? It does not sound sound, in these ways - it may sound like "early stopping" in thoughts.
