It's sad what happened in France, and I wish stuff like this did not happen, but it does sadly. I'm a muslim and I'm against terrorism, and I condemn the attack.
Since this seems to be more about this being another attack by "muslims". I'll just say that these "Muslim" terrorists also kill other muslims, as well as children. There was an attack at a Pakistani school last month, killing 145 people, most of them children, which is forbidden in Islam. http://en.wikipedia.org/wiki/2014_Peshawar_school_massacre
I do not consider these terrorists to be muslims.
These terrorists are also just damaging Islam. These attacks are causing more uproar against muslims in general, but the majority doesn't do this kind of shit, and the attack is being condemned by other muslims as well.
As for caricature drawings, I personally just ignore them. I don't like that it happens, but I can deal with it. Some react with violence, burning of flags and such, but that really just ruins it even more for us.
