I think there should be a NFD category called {{nfd|rel}}, or religious opinion. Like {{nfd|pol}}. It’d say: Religious Opinion. Promoting or criticizing a religion, or belief. Example Deletes: How to Criticize Christians, How to Hate Catholics Example Keeps: How to Become Jewish, How to Learn About Protestantism Say what you think.

Wouldn’t that be basically the same as {{NFD|HAT}}? “Hate based or racist content”
Wouldn’t “How to HATECatholics” fall under " HATEbased or racist content"? Just trying to think of this logically. Edit: Sorry if this came off stronger than I intended it to be.

If written inappropriately, both of the “delete” examples do seem to fit into the current ‘hate’ NFD reason. Unless there’s some other article idea that would be delete-worthy but doesn’t fit into any of our current NFD reasons, I don’t think a religion-specific reason for deletion is necessary.
I just so happen to practice a religion. If there is a specific article about Christianity (which I practice) that happens to be very well-written, I would not want to delete it for any reason.
I don’t see the need personally, but get some opinions here then follow http://www.wikihow.com/Suggest-a-Policy-Change-at-wikiHow
