jcatcw writes "Schools and libraries are hurting students by setting up heavy-handed Web filtering. The problem goes back for years. A filter blocked the Web site of former House Majority Leader Richard Armey because it detected the word 'dick,' according to a 2001 study from the Brennan Center of Justice. The purpose of schools should be to teach students to live in a democratic society, and that means teaching critical thinking and showing students controversial Web sites, says Craig Cunningham, a professor at National-Louis University. He quoted from a National Research Council study: 'Swimming pools can be dangerous for children. To protect them, one can install locks ... [or] teach them to swim.' Web filtering also leads to inequities in education based on household income. Students from more affluent areas have access to the Internet at home and, often, more enlightened parents who can let them access information blocked in schools and libraries. Poorer students without home access don't have those opportunities."
