Caleb speaks of Cal State going ape shit over someone walking around with an assault rifle. When I was in college, one of the ROTC kids got himself a reprimand for toting an M16 openly down the streets of Philadelphia on his way to our school’s rifle range. Oddly enough, perfectly legal for anyone to do; open carriage of pistols is illegal in the City of Brotherly love without a License to Carry, but openly carrying a long gun is not, and Pennsylvania law makes no distinction between legal machine guns and other types of long guns.
I’m not sure this is evidence of hoplophobia. If I saw someone openly carrying what looked like an M16 around campus, I’d probably be a little alarmed too.  It’s not so much the gun as it is that it’s something out of context. I’m not sure my level of alarm would be lower if the person was in uniform.
