The thought that comes to mind after reading this is "protest to much" and also in a very aggressive and condescending way. Not something I would have expected in tone from an accomplished academic. Plus the repeated use of the first name like this: "Come on, Jill, tell me! No!" is clearly unnecessary and parental in tone. Especially considering not only do they not know each other but he has never even met her (last part of article). I think Christensen has been living in his ivory tower to long and getting to much esteemed attention and he simply was completely knocked off balance by someone (of I'm guessing near, or equal, stature) taking issue with what he has said. I'm sure there are many people who have taken shots at his books or theories but not a fellow colleague at Harvard.
