And this is the danger now for France. The politics of this country are increasingly polarised, with the far-Right Front National making large electoral gains.
France is consequently more socially fragmented than ever and this attack only threatens to make things worse, deepening the negative thoughts about Islam.
Also adding to the tensions is the deployment of French troops in Africa to stop the growth of jihadist groups. There are also fears about the numbers of French nationals going to fight as jihadis in Syria and Iraq and then returning.
So many here believe this attack represents a defining moment for this country. And far from simply being an attack of freedom of speech it also amounts to an assault on a nation’s unity.
That is what France is dealing with now and there are many very worried people here.
