freedom
the web was created to send messages from one place to another it has since evolved into something much greater and "evil" but yet it reflects the real world the world is evil what is the point in blocking it. fair enough parents won't want there children looking at some of these "evil sites" but that is what web filters are for but they should be set up by the user of the internet and not by the government.
Another point is that with the current state of the technology the internet is built on its not possible to censor the net because its government programmers vs home programmers or hackers (the original meaning not the evil hacker) its a bit like the sony vs homebrew sony will never win there firmware was too weak to begin with.
Also (from for going on) the internet is way to large for its own good and its time for some world laws to be set because using the internet on a regions laws is impossible because where is the client and where's the server?... if the net is based on region laws then you shouldn't be allowed to access anything outside that region. we need a world order for the internet a bit like the UN but not so pointless.
