My advice to France and French people as a practicing Muslim with background in ME region and having lived there and understand what culture and society there is like:
First of all, I think Prophet's of Abrahamic religions should be left out of satire completely as they are considered holy figures in all Abrahamic religions. Now getting to the point, is not worth it to continue having these satires and not because I am against freedom of speech in your country, I am not. I am just telling you to take political and social climate of Muslim world into context. You have people going through decades of mismanagement, war, civil strife, poverty, corruption, dictatorship, lack of centralized religious leadership and severe disputes between tribes/parts of nations in the ME and greater Muslim world. Muslims are facing a social crisis and it is gonna take more time for things there to change. They don't have a strong foundation for their nations and future and you need to take all these factors into account.
So you have bunch of defeated people who are looking for reason to lash out and sometimes they lash out against their own governments and chaos ensues. Sometimes it is too hard for them to do that and they just bottle in all that frustration. Don't invite that chaos upon yourself as some of those looking for reason to lash out. It's like going to mental asylum where there are people fighting among themselves than you go and divert the attention on yourself. The Muslim world is not thinking with logic right now and they deep rooted issues which require God's intervention to help resolve and I am advising you it's in your interest to just lay off this stuff right now as much as I or others try to change Muslim's thought process, it is not gonna work in the short term and it's better to take this attention off yourself unless you want to be dragged down like how rest of Muslim world is dragging itself down.
I think you guys are underestimating how bad of a shape the Muslim world is in, they can't seem to find direction/guidance at the moment and you should seriously take that into account. Muslims are going to help you as much as they are able to help themselves(take a look at Syria, Libya, Iraq, Yemen, Afghanistan, etc...)
