I'm not calling Grant a drunk or anything else.
I did spend an hour and a half with Mr. Simpson in a classroom earlier this year and then listened to him address the general session of a conference. I was frankly not impressed with him. That is my opinion.
He seemed to me very irritated with the notion of General Lee, placed upon a marble pedestal. Fine.
Yet, it sounded to me as though Mr. Simpson felt General Lee should be removed from the pedestal and replaced with General Grant.
U.S. Grant, on a marble pedestal. This is not ever happening, nor should it, in my opinion. Maybe Mr. Simpson will have his way, but I really doubt it. He's preaching partisan history and again, that is my opinion. YMMV.
