Should you believe David Barton when he speaks about history?

Last week, I wrote a quick post noting that David Barton thought a woman posing as a man to fight in the Revolutionary War was a good thing. Today women can serve openly, but this seemed odd to me in light of religious right concerns about gender bending.
Barton told the story about the female soldier on Glenn Beck’s Founder Friday show. The rest of the show was actually quite interesting with several stories about female, African-American and Jewish patriots. I found myself enjoying the presentation and thought this is important information. Then a question occurred to me: are these stories true?
Yesterday, I posted about how Barton cherry-picked correspondence between Benjamin Rush and John Adams in order to create a fiction about John Adams beliefs. In general, the distortions about the beliefs and actions of Thomas Jefferson and others have created doubt in me about the rest of what he presents. The result is that I feel I must check anything from his organization before considering it accurate.
This is a shame. This is a huge concern and one which provides a powerful incentive for advocates and scholars alike to get their facts straight. Given the status of those who consult Barton, it apparently has not had much effect as yet. However, in my view, those who look for better among evangelicals are not finding it at Wallbuilders.
Confirmation bias is a strong and powerful phenomenon, so strong that it can compromise good intentions and undermine the very ends you seek. I would like to believe but there is only One Being who can ask me to walk by faith and not by sight and it is not David Barton.
