I think things like child pornography, or any rape or coerced exploitation should most definatly be censored. Only the depraved want to see it, and they are likely to act upon their evil thoughts. I think those who provide that stuff should be drawn and quartered (and I mean drawn and quartered).
Everything else should be up to the individual. It is the parents job to see that their children see age appropriate things. It is the parents job to be vigalent. I'm sure it's impossible all the time to protect one's children, but it is wrong to make society responsible for one's children.
