This is just Wikipedia, but it fits the use I've noticed, not just here but also elsewhere. There are matters which “divide” people in such a way a community needs to mark them; so that the one you call puritans still can be happy in the community. It's a little effort for you, just add the tag. The strong one should always protect the weak one, and puritans surely are so weak they need to be shielded by what they think can endanger their mind! :-)
