I picked up my love of Civil War history from my dad, who was a fanatic on the subject. However, I also consider myself to be pretty conservative so I'd appreciate it if you could identify all those historians you say are flaming liberals and why you think they are. Don't want to accidentally contaminate myself.
Oh goodness, there are too many modern day ones to list. You know how liberals always put their spin on history, especially in history books in the public schools. The older the books, the better, but even that is not a guarantee because there were liberals back then too. I usually tend to shy away from the liberal sort of books, and there are literally thousands of books written on the civil war, so if you wanted a complete list, I’m sorry. But a good judge is if the author is promoting or justifying government expanse or unconstitutional measures, while condemning people standing up for constitutional rights, then you can guess which side of t he line they are on. :-)
