Hope you don't delete this one. I know he criticizes President Lee. Sometimes you still need some cancers as sample to tell people of Taiwan which one we can trust and which one we cannot.
Most comments by Cao are so superficial that we can neglect what he says. Think about this how many Chinese living in Taiwan really know Taiwan unless he/she really lives in Taiwanese community and speaks very good Taiwanese. A person like Cao has no such experience how can any Taiwanese people listen what he says?
Most Chinese only know very few things but dare to boast as best expert in the world. Cao is a very typical Chinese. His information most comes from newspaper written in Chinese. I wonder did he ever read any documents of San Francisco Peace Treaty and lawsuit of Roger Lin v USA in English? If not, how dare he make any comments about future progress of Taiwan? That is why I say he is just one of typical Chinese lives in United States of America, even though all information regarding to this matter are free to access through internet without any censorship.
Most Taiwanese people really cannot tell difference between constructive suggestion and destructive comment. In other words, Taiwanese people are too naive to trust someone to say something making them happy at that moment. Then what? Taiwanese people have to clean up this mess by themselves later.
Cao knows how to make some comments to please certain group of Taiwanese people. As long as Cao continues to do this, he can earn some royalty from newspaper in Taiwan. When there is nothing Cao can gain from Taiwan, he will go to his loyal China and Chinese community.
