Every religion has their enemy laid out in scripture; It's important to see that even if there are "enemies" defined in a religious movement, that all of those people still have the option of living the pacifist variant of their religion.

I personally am an atheist, but i am able to see that there are many religious movements out there that substantially improve the life of people. I - sadly - recognize that the moment you mix religion with nationalism you achieve a mindset where everything that isn't according to the most hardline shit in your scripture becomes heresy. I simply postulate that theologians free of nationalist impulses tend to be a much more positive influence on society.
