Columbia University junior and Marine corporal Matt Sanchez has a must-read in today’s NYPost:

DiD you hear the one about the Marines that Columbia University invited to campus for Fleet Week?

Not any time in the last few decades, you didn’t.

But you might have heard the one about the Marine who was told by a fellow Columbia student that he was stupid for joining the military because he’s Hispanic and didn’t realize he was being used for cannon fodder.

It’s actually kind of funny – but when it happened to me during Columbia’s Activities Day last year, I was fighting mad. Not because I was publicly humiliated in front of several hundred of my fellow classmates (any devil dog who has spent a summer on Parris Island gets used to insults), but because of what the incident showed about New York’s most prestigious university.

On the surface, Columbia is all for diversity (good, very good) and completely opposed to intolerance (bad, really bad). On any given day, eager undergrads can speak out for Starbucks employees forced to make coffee with non-ergonomic espresso machines, or call for the school to install non-gender-specific bathrooms.

…All points of view are welcome at Columbia, from Venezuelan presidents to voices from vaginas.

Unless you’re in the military…
