Not talking specifically about Beheading, talking about the violence which has different levels .. yes there are levels to it, just like the insult has its own levels , if I am not insulting his recently dead mother ,yes its not enough to behead me, but for many its enough to start a violent fight that sometimes can turn deadly , we live in a world where road rage can take people's lives right ?
Insulting a prophet it must be very serious for him ( teenager ) hence his reaction ( Completely wrong ) , but as i said, not all French Muslims are reacting violently right ? its because of people tendencies to handle things , some are strong and some are weak, emotionally and mentally .
Solution to this problems is not just banning Muslims from west, or keep provoking them until they are ok with it , its not gonna happen, a solution to this problem involved both sides working together, Muslims make 1.8 billion of total population and their religion and sentiments needs to be respected . Out of 1.8 Billion Muslim you can never predict who will do next for what next event like that. Why not stop the provocations and agitation in the first place ? France is not a Openly Enemy to Muslim world, they do Business with ME and Muslims , they sell and buy stuff , they travel as tourists, but if you can not make a simple rule to stop hurting the sentiments of 1.8 billion Muslims then I will say that you are not serious at solving the issue, but instead you just want to work as Petrol in the already raging fire .
