Iceland shouldn't ban pornography because that is forcing someone's personal value upon a whole country based on questionable reasoning. "[Ogmundur Jonasson] argues that easy access to online porn increases the frequency and severity of sexual violence against women and causes longterm damage for children who view it at an early age." As another commenter mentioned, there is more evidence that porn reduces sexual violence, and it is easy and free to set up a porn filter for children.
I am not arguing that porn is a good thing, but that it's not a government's job to force their subjective moral values upon people by telling them what information they are not allowed to see.
If Iceland's parliament were in fact "forcing someone's personal value upon a whole country", then I would also consider it to be morally wrong. However, the democratic process is there to guard against this sort of behaviour. It doesn't always work, but you haven't shown that it is not working in this case.
I believe you are referring to the reference (haha) to the article in /Slate/. I read that article and didn't find it hugely compelling. Some good points were made in the article, but they weren't even close to a complete argument.
Again, I agree that 'it's not a government's job to force their subjective moral values upon people'. Firstly, when it comes to morality, it's pretty much all subjective. (I actually believe that there is an objective morality; it's just really hard to convince anyone else that my morality is it.) It is, however, a government's job to enforce the morality of the people.
Just because bad things happen in countries where pornography is banned doesn't mean they happen because pornography is banned.
I believe you are saying that banning pornography is an indicator of a bad government and the other governments that have made the same decision are a pretty bad lot. This may be true.
But my point remains: it is a government's job to enforce the values of society. It just depends what we see as our most important values (is it free speech or moral decency, in this case?).
I am not arguing that porn is a good thing, but that it's not a government's job to force their subjective moral values upon people by telling them what information they are not allowed to see.
If you want to see what happens in a country when porn is banned, there are already many examples. https://en.wikipedia.org/wiki/List_of_pornography_laws_by_co...
