This is the fruit of 30 years of Howard Zinn and his ilk, placing ideology over accuracy.
My undergraduate years were in the early 70s, when the older professors were still what I call "classical liberals" - or liberals with honor, if you will. My concentration was in military history, but I did a lot of classics as well. No professor in either the History or Classics department would tolerate fudging or hiding the ball . . . and CERTAINLY not when every "error" was in favor of the student's thesis, as in Belleisles's case.
Those old guys are now retired or deceased (I read with sorrow that the wonderful Dean of the Chapel at my college, Ernest Gordon, recently passed away) and the young Turks are unabashed polemicists for whom truth is secondary to ideological purity.
The fact that Emory is stalling this debate and trying to whitewash even so blatant a cheat and fraud as this horrendous book, instead of debating whether to drop Belleisles off the top of Woodruff Library or tie him to the Seaboard tracks down at the railroad depot, is proof enough for me. :-D
