Ma doesn't want the Dalai Lama in Taiwan...

...but that doesn't mean that he won't come, does it?
Ma's rebuff of the Dalai Lama coming to Taiwan is good news because:
It will enhance international attention to what is happening in Taiwan. In his inauguration speech, Ma welcomed the Dalai Lama to come to Taiwan anytime. Now, Taiwan students and NGOs are thinking about inviting him on their behalf.
According to Lynn Miles, fighting for democracy and human rights in Taiwan since the 70s, this is the way politics should be done by the people:

People! This is what we must all be doing -- taking the movement to the people. People-to-people connections, once consumated, can put an end to this tired, year-in-and-year out chasing after corrupt politicians who are already in someone else's pocket long before we even get past their secretaries.

Wild Strawberries offers us an excellent opportuunity to do this people-to-people grassroots work. Student organizations should be at the top of our list, and human rights NGOs, and so on.

Governments do not speak in the name of the people they are supposed to represent. When it comes to this, evidence can be found in the matter on Taiwan:

Consider this. Virtually all of the world's peoples outside of China recognize Taiwan as a country. Go anywhere in the world and if someone asks you what country you are from, and you say "Taiwan," that is the end of the matter. Pure and simple. So what you have is the people of the world recognizing Taiwan, on the one hand, while their governments do not recognize Taiwan on the other. How then can we call them democracies? They have all been corrupted by the big-money power!

That is why we need to change things on our own! For if we want to see things change, we need to be the change we want to see!
