Tell me that you didn't just say the name of that reactionary Christian apologist and propagandist David Barton, number one on the Liars for Jesus softball team?
Oh crap, yep, that's what you said. Never did a more dishonest person walk the earth, after Peter "Get thee behind me satan" breathed in the dust from the sandals of Jesus....
Barton is a fine scholar and his work on the religious basis of America's founding is solid. Liberal scholars have largely resorted to outright lying in responding to his research. For every one relatively minor error liberals have found in Barton's research, there are several indisputable facts therein. Barton's research is far, far more accurate than that of his critics.
That said, I disagree with Barton on the Sally Hemmings issue. I'm a big fan of Jefferson's, but I suspect that he did have intimate relations with Hemmings.
