I was a history buff back in the 1990s and lost interest; mostly because of all the conflicting alleged facts and theories about just about every topic that I studied, from just about every place I looked.
I found that it's not so much the conflicting theories and viewpoints that make history such a struggle, but it's more at the things that historians don't talk about at all which causes all the conflict for me.
My case in point; I read a book by John Daniel (a three volume series) entitled: "Scarlet and the Beast". In this book is enormous discussion on points in history and facts about the people involved that I have heard no historian ever talk about. The facts within his series can all be verified. The work is stunning.
I traveled to meet John Daniel a few years ago and discussed his work in great detail with him, his bodyguard only a few feet away at all times during our meetings. Some people don't like what Mr. Daniel has to say and would like to see him shut up forever.
History must be rewritten if all the facts and the truth about it is ever to be known.
