I may be wrong, but overall there seems to be a fairly positive strengthening of the sort of decent mainstream Muslim and non-Muslim society in France over this .... on the fringes you hear people trying to rip on "Muslims" or "look instead at the evil West," but most Europeans seem to genuinely feel solidarity on the free speech issue. It's not about blaming Muslims, or blaming the West, it's about uniting against the people who would challenge one of the bulwarks of European society -- a genuinely free press.
Which is a positive.
