I'm so sick of hearing that the cartoons aren't offensive. Ok , so they aren't offensive to YOU, we understand that. They dont hurt you emotionally. By now isnt is obvious that they are clearly offensive to others, and its not offensive to you because you dont beleive in the religion. Its simple.
why is it offensive? IT HURTS US, because it would be as bad in your case if somebody hurt you emotionally, too. Or insulted somebody you love, care deeply about. Your mother, father, sisters, brothers, can you imagine? You will probably retort with something really cynical to this, but that's just expected.
BUT dont go around inciting more hatred purely because you hate the religion.
I have tried to explain why it is such a big deal to insult a holy figure. We love Jesus, Mohammed, Abraham, all in the same measure. They are holy figures of God and it is sad that today insulting them is called on 'freedom of speech'. If you dont believe in them, then fine.
