Still, I actually think most of the hard work that needs to be done in the world is contextual work-- convincing people to be kind to one another in spite of their insane ideological perspectives and differences. Attacking the particulars that need fixing as contextually as possible and orienting those who share your views on the particulars towards the change you're trying to create. That's the shortest distance between two points. That means you need to elevate the good examples inside religions along with condemning the violent and fundamentalist aspects.
Human psychology is really odd and religious belief is even more odd. In most cases you're unlikely to change religious beliefs. So the idea is to target those beliefs that most desperately need changing and use all resources at your disposal to do so.
