History is written by the victor

In today's LA Times, Jonathan Zimmerman, an NYU historian, quotes from Florida's newly passed Education Omnibus Bill, "The history of the United States shall be taught as genuine history and shall not follow the revisionist or postmodernist viewpoints of relative truth. American history shall be viewed as factual, not as constructed."

I guess the author of the bill and those who approved it believe that history just comes about magically, sort of the hand of God thing. No human is involved. They don't believe that people actually write history books. How in a sane universe could such a stupid statement be made part of a state's laws?
