Well, some kind of censorship is necessary, isn't it? Like take for example, racist, discriminatory content, or political content which would have effects that would destabilize the social framework of a country.
If such content were published, there would indeed be unthinkable effects, just think back to the caricatures of certain islamic figures in Denmark a while ago and the whole furore it brought out. Or the political mudslinging ever present everywhere else in the world and all the chaos it brings about.
The good thing, if you can call it that, about political apathy is that it basically means everything is going rather well, otherwise we'd all be feeling very differently about the political side of things, no?
