Too short and broad brushed to understand. Religions are an authoritarian tribal control mechanism. They tend to be more shrinking than expanding unless they are using major force (see medieval Christianity or Islam). You can't really communicate with another type of society in terms of regional belief. They are. You are. If there are no points in common, you can not communicate. If there are one or more points that you both understand together, you can try to communicate. If you have inflexible positions, you may have a modicum of communication, but not understanding, which is the point of communication. Look at our political parties for a good example.
My position is that one needs to be self aware without artificial restrictions to be able to accept and try to communicate with the unknown. I would expect you would be fairly good at this if you didn't enjoy being a fucking troll so much.
