Free speech entitles you to insult others. That is the core basis for free speech. Only when others have been hurt, or critized can you truly understand the basis for free speech.
If JP wants to critizise Islam or Mohammed. Let them. It is their right.
If we as a muslim people are unable to deal with the fact, that others are critical of our behaviour, it speaks more of us than of them.
Mohammed pbuh was drawn with a bomb on his head. But people our people kill in his name everyday. Is that not far worse than a cartoon.
We as a people have to take a serious look at ourselves, and stop acting like hurt children whose feelings were hurt.
