I know that I write on the cross-strait relationship so frequently I'm starting to sound like a skipping CD. But there is a reason it is so prominent a topic here: it is the only seriously contentious political issue in Taiwan, and Taiwanese politics are the focus here.
Take some of the controversies you see in the US and compare them to how people react here. Abortion? Sure, occasional protests, but really nothing at all. Virtually everyone is comfortable with legal abortions. Guns? Bad. Social health care? Great. Public schooling? Needs constant reform, but no partisan divide on how to do it. Military spending? Everyone promises 3% of GDP even if they don't deliver. Welfare? What little there is is good spending. Government funded construction? Pour the concrete. Bail outs? Bring them on. Foreign interventionism or reform of the criminal code? Are you kidding?
The truth is that aside from the independence issue, people here are very much in agreement about how they want the country run -- more or less as it is now, but with no corruption and greater competence. No drama. Just let us get on with our very free lives.
Feel free to contend with my analysis in comments! But I just wanted to explain my seeming obsession with the handful of topics that even enter the sphere of public debate here.
