From what I have gathered, Barton is not a liar, but he is guilty of choosing quotes out of context. For instance, Thomas Jefferson was indeed pro-Christian, and actually said at one point “I am a Christian...” but taken together with many of his other writings that Barton doesn’t talk about, it becomes clear that what Jefferson meant was that he admired and followed Jesus’ moral teachings and believed they were good for the nation...but he probably would never think of himself as a born-again believer washed in the blood of the savior.
I think Barton is only “guilty” of doing what the left does shamelessly: they read history in light of their worldview and that of course gives one a perspective.
I think all in all, his tone and take on the history of the Founders is objectively correct.
Of course he is going to get a fact here and there wrong, that is all part of the gig.
But we have to keep in mind that he has been doing this now for twenty or thirty years, basically alone. Not only does he have no collaboration, he has to fend off the left. So perhaps from time to time he has an overreach. That should be expected, and welcomed.
I don’t hear the left being embarrassed the The People’s History of the United States, which is complete balderdash driven by ideology. I don’t think Barton is the equivalent on the right....but I do think he is the equivalent of mainstream historians who have a worldview, and insert it anywhere and everywhere, without disclosure, without apology...and often without even knowing it.
Barton is a huge breathe of fresh air.
Were that there were thousands like him.
