You obviously don't think things all the way through.  Our university campus is essentially co-located with a hospital.  It is SOP for nurses (and others) working at all hours to be armed while going to and from work.  A law forbidding being armed on campus might be a problem for any person with a legitimate reason to at least feel safer traveling - when the route takes them though the campus.  An accident might result in being charged with an offense.  Then there is the matter of a person who isn't young and hormonal as you worry about:  do they lose their rights because of your concerns?  Laws are blankets.  Freedom should maximize options. If MOST people have no need to be armed on campus, something I agree with, why do you want to make it ALL, even those who perhaps should be?
