I do not believe in censorship when it comes to the internet. I strongly believe that ALL knowledge is good knowledge as long as it is in moderation. If you object to something, such as pornography, violence, etc..., than DON'T look at it. No one forces you to go to certain sites. For some people, these things are there careers, and whether you disagree with what they are doing, no person has the right to tell someone else they "can't" do it because they don't want to see it.
Also, once you start censorship, than where do you draw the line? What is considered porn, and what is considered art?
For example, what makes this very famous Botticelli painting ART and not soft core pornography? Censorship belongs to closed-minded individuals, not to those who think. This is clearly art, but some have tried to say that it is more. I for one, do not want someone else doing my thinking for me and telling me what is acceptable for my eyes. I have my own brain, I can decide for myself.
