Obvious to all? Nope. Not at all. You're wearing your rose colored glasses... You see, the only reason to feel out of place would be if they made me feel that way. I associate with people not of my church all the time. No big deal there. Shouldn't have been in this instance if they didn't have their own issues.
I was being sarcastic; again (still!)
Of COURSE you could handle it, that's what mature people do; but perhaps they would have felt as though they would have cleaned to 'cleanse the Temple', so to speak, before they could actually USE their possession.
MORMONs make a BIG production out of opening a new 'temple' and invite the WORLD to 'come see what WE have!' (that you don't)
Then, when the crowds are gone, the cleansing begins.
Any ex-mo's know just EXACTLY what goes on during this 'cleansing'?
Heck...
Any MORMONs know?
Do they Cast Out Demons?
Do they sprinkle Holy Water?
Do they Annoint things with Oil?
