Nice get and link. Excellent essay. Thanks for posting. I do have a couple of issues with the writer, though.
For one thing, he does correctly identify the new historiography as Marxist. What is needed here is a separate study by historiographers and, frankly, street detectives outlining the growth of the Marxist cabal in opinion leadership and historiography. This will be a major work and will necessarily involve battlefield interrogations of the KSM types running the nodes of the cabal. Unlike historians and scholars, these people are spies and criminals and need to be treated as such. An article a few years ago described one such opinion criminal running his game in the entertainment industry out in California -- the guy was nodal, but not a Hollywood Name. Instead, he was a low-profile yardmaster in the marshalling yard of Hollywood opinionmaking (cf Oliver Stone's agitprop films, W. e.g.), and he was very much a ringmaster of the BDS circus out there.
The second point your essayist misses is that it wasn't the National Park Service that was responsible for changing the Park Service's historical reference material distributed at the nation's military parks -- it was William Jefferson Clinton, hisself, doing politics through the Park Service, with Eric Foner and James McPherson as his Red scriptwriters.
The whole point of vilifying the South is to break resistance, which is buttressed by the South, to the Marxist takedown of America. And the South-baiters on this thread are working that grift for all they're worth.
Why they are still here is what I wonder at. They're doing Bill Clinton's politics on Jim Robinson's website.
Wow, that sounds series. Thank God none of that is happening here.
And all the while claiming to be such staunch conservatives!
