"walking around in goatskin loincloths while claiming to be divine messengers preaching about creation."

I think the real story is becoming more clear. These guys may have some mental problems. Considering their buttocks were exposed, there are also some hygiene issues in a modern society.

I think Graham's standard of being considerate of others is the key here. No matter what the cultural context, curtousy and common sense should rule the day.
