You're right about the commentary. That's the real story.
It's extraordinary that these 50-year-old alumni are withholding donations from their alma mater because it is actually attempting to enforce the law. (My favorite is the place where the alum puts the word "underage" in quotation marks, as though the laws of the State of North Carolina are some kind of mere formality!)
I also love the way "Al Adams" mentions tea parties and poetry readings as examples of dry events. Apparently this guy does not have a lot of imagination. I also love the way he equates lack of alcohol with lack of a campus social life. Because, after all, it's a scientific fact that it is impossible to have fun with your friends while sober.

I guess after 50 years, this guy still can't work up the nerve to talk to a girl unless he's smashed, and expects that all the guys at Duke are just as limited as he.
