Steve, I am going to disagree with you on several points. Your observation that a PhD in history does not make one honest is true, of course. There are both good and bad historians, as there are good and bad in any walk of life. I suspect that you have not read much history and that you underestimate readers of history. Not everyone is hoodwinked by glossy books in a shop. In fact, much of good historical research goes unnoticed by the general public.
I also disagree with your comments about "obvious" right wing bias on the part of Teribus. For the most part he presents facts, some of which are largely ignored by those opposed to him. Again, I think you have not read much history Steve or you would not be so quick to dismiss many writers of history as biased or worse. Just an observation, not meant to insult you.
