Your comment is quite disingenuous. The major ISPs parental filters have all suffered numerous false positives and varying commitment to fixing the problems. The porn filters particularly often block access to sex education, anti-bullying, and support sites for young gay/transgender etc (also I believe some charity sites for women suffering from sexual and physical abuse at home). If someone opts out of the default filter they are ensuring that people in their household can access support they may need, not just letting porn in.
