I hate David Barton's fake history and anti-American theocractic revisionism

But that's ok, according to Barton himself, apparently.  Barton is a fraud when it comes to history; he is not an historian, he promotes false information and inaccurate ideas. He is a right wing nut, who seeks to impose and coerce Americans, trying to force us to conform to his toxic religious beliefs.

" When fascism comes to America, it will be wrapped in the flag and carrying a cross." attributed to Sinclair Lewis and/or Huey Long

Definitely from Sinclair Lewis:
From It Can't Happen Here:

"But he saw too that in America the struggle was befogged by the fact that the worst Fascists were they who disowned the word 'Fascism' and preached enslavement to Capitalism under the style of Constitutional and Traditional Native American Liberty."

From Gideon Planish:

"I just wish people wouldn't quote Lincoln or the Bible, or hang out the flag or the cross, to cover up something that belongs more to the bank-book and the three golden balls."

That applies to Jefferson, Madison, and the rest of the founding fathers as well as Lincoln.
I see that kind of theocratic fascism in Barton and the Tea Party, and the far hard right conservatives who celebrate intolerance while attacking our real freedom, including freedom of and from religion.
