As argued above, the average child can probably find instances of pornography in the real world far easier than they could on the Internet. Don't carry the relevant groups. I personally think that even if you censor stuff on the Internet, children will find access to pornography in the real world from siblings and friends. It is sad to see that children remain the most oppressed people in this world. Sure, the Internet can be a waste of time, but so can other things in this world.
Information is easy to find if one knows how.
The communication revolution should be based not on how we talk to each other over the Internet, but how we use the Internet to do our work, to find what we need, to entertain ourselves, while there are millions of other people doing exactly the same thing. It is how individuals interact as they go about doing their own thing and not how a society functions as a collective. This includes television, radio, movies, and print media. The interactive nature of the Internet is the key to this. The media usually cites bandwidth as being a problem, but the bandwidth problem is also overrated by the media.
