No, that's the same "common sense" we used to justify discrimination and other abuses towards people who were different in some way, e.g. by race, or by sexual preference (e.g. homosexuality). And at the time in history the discrimination was happening, most people considered the discrimination normal.
Heck even we still have problems with society discriminating against young people, and especially teenagers, by the way. So I really care about young people's rights.
But I still think these draconian content laws are unacceptable, they are replacing one form of abuse (pedophilia), with another by the state (sending people to prison for possession of data).
