I see the religious part of this CoC as purely incidental to the source material (it being 15 centuries old and aimed at christian monks). It's clearly not meat to be taken serious, even though I'd agree with a lot of the common sense points listed. Now, being a bit annoyed at the religious implications is not being really angry and blowing things out of proportion. Being annoyed still leaves room for discussion. What I meant is the major poop flinging through major publications that will undoubtedly follow over the next few days, activating large swaths of those people I mentioned. Those who thrive on nonconstructive anger. In general I'd agree with you, just leave religion out of it, even when it's (or especially?) in a joking manner. Edit: Typo
I see the religious part as being the entire point, since it comes from a religious order. The very first rule is about loving a particular deity. If we were to go back in time and find these people, what do you think would offend them more, “I hold grudges” or “there is no god”?
I daresay that a difference in opinion like that would probably not trigger most people back in that age in the same manner it seems to do so now (on both sides - I'm not picking on one side here).
While there have been people who have done things like this in all ages (and also over believing there is NO God, as opposed to just the wrong one), your statement is not as accurate as it could be in most cases if you take into account the context of those wars.
That said, Benedictine monks would not be at or near the top of my list for people who would get all triggered, angry, and go to war over you disagreeing that God exists.
Yes, people fiercely defend what they love and believe. But it's possible to do so graciously and firmly without being angry or freaking out that someone disagrees with you (I am not referring to you specifically, but you, myself, our readers, mankind, etc).
