Are there people in the West still willing to die for their country? I know a lot of people, but none that would die for Norway. So when you talk about first amendment, I can't help but suggest that the reasons for censoring were more practical.
One person can say a bunch of bullshit, and another person can get annoyed and wanna kill this person. The logic for not saying bullshit is not that it's wrong or anything moral/etiquette-related. It's a more practical dilemma. "Is this joke so funny that the episode will get so many views that risking my life and the life of those working with/under me is worth it for this particular joke, regardless of what ethics should dictate?"
Laws, and particularly laws like the right to freedom of speech and the right to freedom of thoughts, are illusionary. They are there as guidelines for how most people would like things to work, but our very nature and instincts contradict many of these guidelines (young children, unconditioned by the rules of society and more in tune with their very nature, can be considered pretty gruesome and evil in their ways of systematically breaking down the fat kid or the ugly kid), so every individual can decide to either blindly expect everyone to follow the law, or to guard one self and ones loved ones in the event that the law fails them. In reality, freedom of speech and right to freedom are rules that are violated daily. To expect that they won't continue to be violated for all eternity is naive. Btw, I'm not calling you naive, I'm just saying in general to underscore the point I'm trying to make. You can't depend on a law that says you have the freedom to express yourself however you like when there are crazy people out there who don't care about any laws or amendments. Or you can, but it's risky, and will only serve an illusionary goal - your freedom of speech.
