To everyone else it is. In fact, MOST Christians never knew baptisms were done in the nude and does not know about the crucifixion being done nude. With that, they have all kinds of ideas and Christian Naturism is the farthest thing from their minds. If they think just being a normal person in their back yards in nude would give them serious pause and alarm, think what would happen if they thought it was in Christianity?
It would be practically a freak show to them!
