Even if a 'perfect' censorware program existed, we still wouldn't support it, because this still promotes the belief that parents are always right. A more troublesome issue is the degree to which politics determines which sites get blocked. Some particularly puritanical programs, for example, deliberately restrict any websites dealing with controversial subjects such as homosexuality and abortion. Even software purveyors admit that there is a limit to cyber screening. That's why education is key.
Nothing beats teaching junior to be cyber savvy.
Even traditionally censor-happy Singapore has realized that restricting Internet access is futile. The island republic's initial attitude towards the Web was to censor. Now, the government blocks only 100 sites. Instead, Singapore focuses on educating its citizens, with government-sponsored workshops on Internet safety. It's a lesson that China has yet to learn.
