Not suggesting pants wearers are not part of the self assured. I am suggesting that to wear a kilt everywhere as daily garb in the US puts you in a group that requires a good sense of self worth that most do not possess. They are adults no longer subject to teenage type peer pressure and will consider doing something that is out of the normal. Until it became a part of the counter culture you would call them free thinkers.
The ones that ridicule something different are the sheep trying to protect their own sense of normal. They are very resistant to change.
Does that clarify anything.
