The context for this resolution was specifically aimed at curtailing criticism of religion, and was initiated and relentlessly driven within the U.N. (for a decade?) by the OIC (Org. Islamic Cooperation).
So the question about the Danish cartoons wasn't really rhetorical. In this example, the resolution would call on the Danish government to
censor the cartoons criticizing Muhammad. It could be applied also to stopping Neo-Nazis in the U.S. from parading through Jewish communities, and so on.
Another non-rhetorical question is: Who do you think is unbiased and smart enough to judge such situations?
And another: Isn't free speech most critical when tyranny is on the march?
My own take is that - in an imperfect world - we should err on the side of strongly defending free speech.
