Because it needs to be done.
Columbia University needs to Tighten Up. Way to invite Ahmadinejad to speak at your oh so heavy with Ivy hallowed walls. You've pretty much confirmed for my father that my boyfriend is a wacko leftist weirdo for attending graduate school Columbia. Way to go, assholes.
Now, Columbia, if you're going to do something this stupid, you better man up and be prepared for the firestorm. I can respect you for "robust debate" and I am all for free speech, but you better damn well understand how this makes you look in the eyes of many Americans.
And while you're at it, you could consider a little paint here and there where the students actually have class, not just prettying up the outside all the time so none of the passersby suspect that the historic preservation building is held together with duct tape. It's disgraceful. And I went to a PUBLIC SCHOOL, where a map fell of the wall during class and hit me on the head, so I know a little about class in shitty conditions.
