My opinion:
We (Germany) have age rating for topics/games etc. We have that for videos, DVD, PC games etc. It is highly critized, but I still consider it correct for people under 18. The prob is, this age rating does not change, there are Marilyn Monroe films that were rated above 16 and they're harmless, just a product of these stuck-up times.
Disadvantage: Gamers/Viewers above 18 have to go through some trouble to get what they want - and this bothers a lot of adults. Still, I believe, for the sake of young people this age rating should be kept as it is.
Problem: Forbidding stuff for under 18 makes curious, the internet allows many accesses to games not suitable for kids.
I guess, censorship will remain problematic: It reduces adults to kids, cause it takes away self-responsibility - on the other hand: are all adults self-responsible cause of their biological age?
When I'm very emotional(angry): I would like to censor everything dealing with violence, racism, intolerance, sexism, pornography - But I know, this will only make these topics more interesting when not accessable.
And censorship takes away personal freedom...
So, to answer your question, Womble: I plead for a definite: YENO (Yes+No)
