I came in to say essentially the same thing as Cormac, but with a twist. I can divide theists into those that A) dogmatically follow an Abrahamic creed on the one hand, and on the other hand B) those that (x) seek out their own truths , syncretist or otherwise, or (y) follow eastern thoughts. I can also divide atheists into A) dogmatically so and B) the agnostics. The B's get along just fine with everyone unless they attack us. The A's are each arrogant and seek to antagonize everyone else.
