Excellent article. As Gina Miller points out, David Barton's greatest contribution to scholarship is his painstaking accumulation and sharing of primary source documentation - the Rosetta Stone of honest historical research. Barton has amassed one of America's greatest libraries to document the history of our founding. What really ticks off the America haters about David Barton and WallBuilders.com is the powerful resources they've placed at others' disposal - because primary source documentation speaks for itself.
It's hard to contend with primary sources. One must debunk the letter, book, compact. WB has preserved these from the left's "ministry of truth" (revisionism).
