I have none.
Or, well, I have only a couple. My first thought is “why should I care about this?” The Class of 2007 had a decent reason to be angry about their commencement speaker: giving SJT the top spot was a bit like trying to sell someone back their own bowel movement. (Did I just compare SJT to a bowel movement? That’s unfair. Sorry.) As long as the administration isn’t actively insulting us with their choice of a speaker, though, it’s just too minor of an issue to show up as a blip on my things-about-GW-that-piss-me-off-dar screen.
I agree with Pat: an intellectually stimulating commencement speaker would be nice. Come to think of it, some chocolate ice cream would be nice right now, too. I’m not going to care much if I don’t get either of those things; they’re about equally important (er, unimportant) to me.
To repeat myself: this is SO not an argument worth having.
