Perhaps people in Kansas are different from people in other states, such as Arizona, Michigan, Ohio, New Hampshire and the Commonwealths of Virginia and Pennsylvania (just to name a few)?
People in the other sovereigns have no significant problems with people OCing; it's done all the time. No blood flowing in the streets, shoot-outs at street corners or significant losses of life over fender benders.
I took my wife and son to a nice restaurant (no plastic cutlery) the other day while OCing. Nobody ran screaming from the establishment, SWAT teams weren't called in, nor did bullet holes suddenly appear in the ceiling or floor. It was an uneventful day.
Then again, maybe people in Kansas are different.
