As FoxtrotUniform pointed out, this discussion is definitively healthy for the Monastery. I would like to add that it's healthy for any community.

I dislike the image you're referring to, and I dislike the messages on the home node you're referring to as well. But I think that someone that is very comitted to Christianity may be offended by other statements on this site. I understand your point of view to "draw the line" somewhere. The problem is just to define, even on a case by case basis, where to draw it.

Maybe some kind of consideration with voting on home nodes would make sense?
