On my Facebook photography page, I started blocking religious terms. It automatically hides comments that include religion. The author and their friends can see the comment, but nobody else can. It has eliminated contentious threads.

There are so many people who comment of other people's photos stuff like: God is the best artist, god's creation, god's paintbrush, and on and on.

I'm not religious (although I have a BA in Religion) so I find it alien that people comment that way on photos.
