I didn't see the post asking me to clarify my views until now, but better late than never I suppose.
My general view is that society should be moving toward unity and should move toward separation/independence if there is real benefit. The separation of China/Taiwan came about due to a civil war between the Nationalists and the Communists. As neither had clean hands, in the slightest, I don't view either side as having any sort of morally superior high ground as some of the other posters here. The depiction of Taiwan as somehow a superior government or morally superior is not something I find a fact, quite the opposite really, so morally speaking I see no relation between the two governments and whether one should be there and the other not.
I also maintain a pro-unity view because I live in Canada and I think Canada should stay a whole country. I would not accept a separatist Quebec, or a British Columbian breakoff, or an Albertan firewall or a return of the Dominion(?) of Newfoundland/Labrador. So why would I suddenly turn my philosophy around when it comes to a foreign country? I'm not a hypocrite, so I won't change my views simply to suit my country's desire to have a weaker China.
Further, I don't think it right for the Chinese to maintain this artificial split between them, creating a chasm between families and friends. Moves toward more open borders, more trade, more relations and more freedom of mobility is a general plus.
Just like I don't like racism, I don't believe in ethnic nationalism, such as with Tibet or the more recent Turkic movement. And this applies to Taiwan as well. Taiwan has its own ethnic groups, beyond the Chinese groups that moved over there after the civil war, and I think that they can and should be included in an overall government. The solution to minority rights is to give them, not to separate them from society and create new countries. Would I want a Chinese-Canada carved out of Toronto here? That's idiotic and I wouldn't apply that to China.
The long-term consequences of the highly profitable arms trade and the highly attractive status of Taiwan as a military staging point for the United States and any other power poised against China, makes Taiwan an incredibly useful ally to have and to exist. Generally speaking, this situation is not beneficial to humankind in the long term. There should be peace in East Asia and that is best accomplished through a proper unification of China/Taiwan (and then after that, a proper unification of Korea and then after that, settle peace between Japan and everybody else).
I also believe that with the deteriorating economic condition of the United States that the ultimate future of Taiwan becomes more and more unstable so long as it stays independent. Whether China or the United States makes a move as they view a more enticing scenario for themselves in terms of territory and power, either way it is not good.
I also believe that the economic conditions in the area are best suited for unification. It will improve business, trade and middle class power. For instance, the current Taiwanese budget is heavily geared towards military defence, whereas China spends as little as 2.0% of their GDP by CIA estimates on the military. Given a unified China, Taiwan's military budget will plummet, which further improves their social network of education, healthcare and infrastructure. Taiwan's superior economic position is not due to democracy, it's due to good land and good government; that is, Taiwan's prowess is no better than China's power provinces.
I do like democracy and because of the improving political conditions of China, I am cautiously optimistic about their future. As China's government and it's people become more participatory, Taiwan loses what little argument it holds other than ethnic nationalism, on further independence bids. However, according to polls, most Taiwanese swing toward status quo, or unification and not independence. I think that is primarily held by the native tribes of Taiwan, for good reason (historically they've been heavily mistreated). Taiwan is pretty much run by factions made up of military families backed by the mafia (this would be libel if I were more important :P ) and China is run by the rich. It almost seems like it should be the other way around.
