From the Malaysia Star, an excerpt from the Vatican's statement on the Mohammed cartoons:

"The freedom of thought and expression, confirmed in the Declaration of Human Rights, can not include the right to offend religious feelings of the faithful. That principle obviously applies to any religion," the Vatican said.

"Any form of excessive criticism or derision of others denotes a lack of human sensitivity and can in some cases constitute an unacceptable provocation," it said in a statement issued in response to media demands for the Church's opinion.

With all due respect to His Holiness, I think they got this one wrong. There is no right of not being offended by others. The reaction to the offensive material, though, is up to the viewer and parts of the Muslim world have not aquitted themselves very well.
