I should have left the word Christian out. It was not really needed. By the time I saw what it had spawned, it was too late to edit.

Yes, it really does boil down to just that word. We can speculate about the reasons, but the effects on a large forum like this one are predictable.

The problem with excluding religion is that it's relevant. Imagine excluding any other branch of philosophy (science, math, photography, morality, logic), and the effect it would have on conversation. It would make no sense, and it would make it impossible to have meaningful discussions about many topics, as well as impossible to arrive at certain truthful conclusions about them. To exclude religion is essentially a (very closed-minded) religion unto itself.
