Well Jerry there are certain taboos in different cultures, and while something might feel right to some culture would feel wrong to some other. Same reasoning applies to religion, even legislation as you pointed out in one state.
My take on the topic, and in life in general, is to respect other people's opinions, beliefs, as long as they don't cause harm to others.
Hiding oneself 's private parts (or any part depending on culture, religion,...) is a personal choice based upon his conviction, which is part of the freedom I believe every human should posses.
Thanks for posting on such a delicate topic, in such a fun way
