Was Charlie Hebdo a Christian magazine? Not in any sense or stretch of the imagination. Charlie enjoyed attacking all things sacred, and no faith was off limits. Of course, the difference between Muslims and Christians is that Christians believe in a God that is bigger than the magazine and doesn’t need His believers to kill in His name. Allah, on the other hand, demands it.
Here is an example of Muslims killing two birds with one stone. Here, we see Muslims storming a Christian school in response to the Hebdo cartoon. Does that make sense to any sane, rational human being? Of course not. It does, however, make sense to some Muslims in Pakistan.
