I still retain some affection for my alma mater, but this week disgust trumps fond memories. Here is the column I wrote last year on the subject. Now that President Bollinger has issued his free speech explanation I await Columbia’s invitation to David Duke (actually an ally of Ahmadinejad), or perhaps to one of Seung-Hui Cho’s several Internet fans. Won’t they? Oh, well, let’s see, Cho killed college students, whereas Ahmadinejad is killing American soldiers. Of course, of course. And with no ROTC at Columbia, there’s zero chance that any Columbia students are within Iranian crosshairs. So that’s okay then.
