Lots of good comments in here.
I think there's a little bit of a double standard in regard to how pagan religions can be discussed vs. how Christianity can be, but that it's an unavoidable one given their relative cultural status and influence.
Those of us who are followers of neopagan or reconstructionist pagan religions tend to be perfectly comfortable with and accustomed to seeing our religions (or more usually, those of our pagan forebears, which have no connection of contiguous tradition to modern practice) spoken of lightly, and are usually not sensitive to such comments.
Since, as has been noted, the objective of moderation is to keep the peace, rather than to aspire to some perfect principle of fairness, this means that it's rarely going to be needed in regards to discussions of paganism. And I think that's ok.
That being said, from everything I've seen of moderation here, if someone were being directly or deliberately hurtful in regard to my religion, I have confidence that the moderation would step in appropriately. Either if they happened to see it, or if I were to report it.
