I am not saying that the victims of this attack "had it coming" or that their deaths were justified. What I am saying is that we have to draw the line between grieving loss and valorizing a racist publication that reinforces a political climate hostile to Muslims and other minority groups in France. There's no right side here, just a bunch of dead people, their families, and living people who will have to deal with the oncoming backlash.
Ahem... This is not a zero sum game.
You can disagree with every single group involved with this or simply disagree with some of them to varying degrees.
Did the magazine make racist and islamophobic cartoons? Some people seem to think so and they certainly did their best at insulting everyone and everything equally, because they thought that ALL the sacred cows deserve a kick in the name of the freedom of speech.
Did the terrorist murder these people? Yes. Did they have the right to be angry when their religion was mocked? Yes, but that does not give them a right to murder people.
Are moderate muslims getting blamed for this? Yes, islamophobes are having a great time right now. Should moderate muslims declare that they do not support these acts of terrorism? Yes and many already have done so, particularly in France.
Are the moderate muslims "the greatest victims" of this attack? No... I think the magazine employees and their families have suffered more, but the islamophobes are certainly using this to attack all the muslims.
