You're dragging some baggage in there. Of course a wartime anything is inappropriate in a "non-hostile" place. How about a peacetime weapon in a public place of indeterminate hostility?
For that matter: doesn't the incompletely-enforced prohibition of personal arms make a place inherently hostile?
A campus should be inclusive and non-intimidating. If you want women, minorities, foreign students to feel comfortable and secure, then arming self-entitled white males to strut around campus with deadly weapons for no reason other than pandering to their own deep insecurities is not the way to do it.
You don't suppose some of those women want to be able to protect themselves from the real rape culture?
I also wonder how these "women, minorities, foreign students" would even know that others are carrying concealed weapons. (Further, a lot of us wonder how these special snowflakes will cope when they graduate and are in the real world, after being coddled all their lives.)

Consider the Zimmerman-Martin case. Martin, taller and with the advantage of hitting first, was on top of Zimmerman, pounding his head into a concrete sidewalk, and Zimmerman nonetheless was able to draw his gun and shoot Martin.
