Fundamentalists have no tolerance for anybody that thinks differently (including members of the same religion) and are easily incited to kill, maim and slaughter everybody perceived by them to be "different". That is the problem with religion: Depending on infection degree (meme infection), intellectual capabilities, empathy and common decency get suspended and replaced by easy recipes that often involve strong forms of aggression.
And no, I am not intellectually lazy, rather you did not understand what I wrote.
I understood what you said as an incredibly narrow characterization of behavior and disposition of people of faith, focused on the limited dimension of aggression in conflict, as if that were the most dominant human social experience. For those of us who live generally full lives with different kinds of interactions, it is not. I've set foot in North, Central, and South America, Asia, Africa, Australia and Europe and have looked different types of people in the face, acknowledge our differences and still share something in common. I have not gone into war zones or areas dominated by people intent on killing strangers and I have been just fine, enjoyed the people, the culture, the history, the food, etc.
It's pretty arrogant and not very "tolerant" to look down on people of faith as if they're programmed as outdated robots with a few lines of code -{if(other_person != fellow_believer) action = kill;}- whereas you are a more sophisticated model.
By this measure of "easily enticed" and considering the amount of people who practice a religion, we would be extinct already. Religious people coexist everywhere in different manners without violence and would rather continue to do so until their respective end. For non-muslim religions, the eschatological agent is the one that will rid the world of the non-believers. The faithful take no part in that, would prefer not to. The problem with religion is that it is practiced by imperfect people, all with their own varying degrees of intellectual capabilities, empathy and "common decency" (whatever that means).
