Things like the government, things that the public literally shouldn't know for very good reasons, that sort of thing should be censored. However, from an entertainment perspective, or things like porn or swearing or violence, that shouldn't be censored, but should be educated about and forewarned so people have the free choice not to partake in it if they don't want to. That's one of the many reasons I disagreed with Wikileaks while most of my liberal friends (and I'm pretty liberal myself) supported it - the fact is, that site couldn't tell the difference, or didn't care about that line and just printed literally everything without a thought to whether it would or wouldn't be sensible to do so...
