This is rather bad history. It's funny, this article starts by talking about how the Nazis were unable to escape the worldview of the regime they were in, but we have cliches and slogans of our own, almost as rigid as those of the Nazis, and the author is recasting history to fit those slogans. Don't like something? Connect it to Naziism, racism, the South or slavery, the bogeymen of the establishment. Political correctness beamed through the television 24/7/365 permeates our thinking, and defines the terms of social and political debate.
