They did it in the name of their own ideals of Islam. Islam itself is a religion teaching of peace (which is what all Abrahamic religions are, in base).
They screamed Allah but they believed in their own thought process. They are just terrorists who happen to use their faith as an excuse. It's entirely political.
If you wanna throw numbers around, 11 million muslims were killed by fellow muslims. Simply political instability.
90% of terrorist attacks were actually carried out by non-muslims. Shall we not cater to the jews due to some jewish extremists? Whall we not cater to the entire leftist ideology due to a few (damn commies)? Shall we not cater to anyone who is latino?
Seriously. I don't care if you were being sarcastic with that picture, but someone made that and it sounds like something I would find on my dad's facebook feed.
