and that is how it should be

Christianity, in its essence, does not promote peace as the author suggests. It does so only on the surface. Dig a little further and we come to the real essence, which can be summed up as “I’m right, therefore you’re wrong.” And people who are certain they are right will invariably feel compelled to correct those who are in error. Combine this with a martyrdom complex—the widespread belief that Christians are being persecuted and attacked by a hostile world, and are therefore obligated to “defend” themselves—and you’ve got the combustible mixture that sets the stage for a “pre-emptive” strike. Finally, add to this the doctrine of eternal damnation—a revenge fantasy—and you’ve got all the ingredients required for pro-active militancy.

You could say that Churchies are now growing a faith that their God won't protect them when they need him most.

Nearly as many shootings in church as school aren't there?
