Is the Chapel Hill incident hypocritical of Anti-Thiests?

I agree, but surely the Quran doesnt teach them to kill everyone who betrays Mohammed?

Sure it does. You're supposed to kill everyone who isn't in the religion with you, including people who leave. This isn't a particularly uncommon command either; christianity has it too, it's just that christians are less likely to take that part literally. They've entered the stage of their religion where all the inconvenient things are to be interpreted, which doesn't appear to be a stage that has fully swept over the younger islamic religion just yet.

The muslims who did this are unlike most muslims and shouldn't sum up every single muslims, althought many can be batshit crazy!

Here's the thing: there's a difference between the religion, and its adherents. The French shooting doesn't sum up the character of every muslim, but it does sum up the core concepts of that religion. Those muslims that are good people, of which there are many, are that way because they are applying their rationality and compassion to their religion, in varying degrees, and excising those parts of it that conflict with those senses, not the reverse; Islam isn't instilling them with anything moral, they are subtracting the immoral teachings from islam until they produce a religion they find moral.
