On each of the three examples you gave, an article addressing more than one belief and contrasting them would be valid for either an "ecumenic" or "open" tag. The difference would be in the type of posts which are tolerated.
Somehow I’ve managed to read or skim 262 posts.
Reminds me of raising kids or herding cats.
Good luck, RM, you are going to need it along with lots of patience.
