britexpat,
The world is so diverse in all its aspects.
At any given time there is something weird or unusual happening in some spot of this planet or even universe.
Do we really have to worry about every single minor isolated episode like this one? If yes, we would not have enough time to live our own lives.
As I said, it’s precisely in your country of origin (and not France), where a real huge problem is! Any slight interpretation of blasphemy is certain to kill innocent people.
There, you have a real problem as it’s a national movement of fanaticism!
