Uh what? When is unnecessarily(hint I use this modifier for a reason, please don't remove context from my arguments) offending someone ever productive?
Do you not realize that this works to needlessly incite people and helps drive terrorist recruitment?
Really? As somebody said earlier, if a fucking cartoon drives people to radicalise, then absolutely anything else would have done that too. They are absolutely not unnecessarily offending people, there's a context here and they basically couldn't have done anything else than having Mohammed on their new cover!
It's also surprisingly respectful, as they just said in a press conference:
"Look at him, our Mohammed is much nicer than the perverted version the terrorists are claiming to follow"
