I see your point, as our main difference is I have confidence in the central government while you don't. You aren't happy with "reforms here and there" because they are not significant enough. You would rather adopt a radical approach to root the communist party out completely and hope that the succeeding government will, I assume under the help of the more developed countries, establish a system that is truly beneficial to the general populace - which is something that I find hard to believe.
Lets say I assumed correctly, and you are for Western assistance in building a democratic political system. You say that CCP lacks credibility, that no well-documented changes are noticed by the world - well, economic growth and the drastic decrease in poverty obviously don't count in your eyes; however, given how the US and other western countries have acted in Kosovo, Iraq, etc, it seems to me and a lot of others that they are simply not interested in implementing a system that would actually work. In fact, it seems that the civil war stirred up by the US occupation has claimed far more lives each year than under Saddam's rule. In this respect, the US which is hailed as the leader of Western Democracy, is not exactly credible in my eyes either. After all, they are not Chinese. In this matter, my fundamental belief is that ONLY Chinese will put Chinese interests at heart. Western interference in the construction of a country's political system will do more harm than good.
But then of course, I could always make incorrect assumptions - maybe you don't believe in the West anymore than I do. Then I have something to ask you: Where does your confidence that whoever takes over will be better than the CCP, which, even though made atrocious mistakes, has successfully achieved international recognition, come from? "Anything is better than those looting and corrupted communists" is simply not a good enough argument to convince anyone.
Yes, Taiwan Democracy seems to have claimed a victory, back from the laughable circus it once was. I applaud that, as well as Ma's more open and communicative approach with the mainland. It is a pleasant occasion, when Taiwan Chinese could gradually bring their political ideas over and influence the general Chinese populace, which would in turn accelerate political reforms. Nanjing has had its first televised election of officials - not the sign that democracy is fully embraced, but definitely a step in the right direction. Under any context, keeping a hostile attitude towards a government that had successfully garnered respect from a majority of its citizens, is simply not a wise thing to do.
