Consider the fact that vast majority of search queries will not be affected by the censorship. Your actions are depriving billion+ people from these queries. Think of all the things kids could have found out about science and western literature by better search that they currently aren't.
Finally, I would to leave a note on cultural aspects. Being in western world, we assume that every culture in the world wants democracy. We firmly believe that every culture resents censorship. From my contact with many asian folks, I have changed my assumptions and such belief. Chinese culture is fundamentally different. Government is not looked at some agency that people allowed to govern but rather an agency that is charted to protect culture even if it is at the expense of individualism. My theory is that even if Chinese government was toppled, the replacement would still have same characteristics because that is the expectation that people have from their government.
