"Unfortunately, most Americans know little of this progressive history. It isn't taught in most high schools."

Asserts The Nation:

You can't find it on the major television networks or even on the History Channel. Indeed, our history is under siege. In popular media, the most persistent interpreter of America's radical past is Glenn Beck, who teaches viewers a wildly inaccurate history of unions, civil rights and the American left. Beck argues, for example, that the civil rights movement "has been perverted and distorted" by people claiming that Martin Luther King Jr. supported "redistribution of wealth." In fact, King did call for a "radical redistribution of economic power." Using his famous chalkboard, Beck draws connections between various people and organizations, and defines them as radicals, Marxists, socialists, revolutionaries, leftists, progressives or social justice activists—all of which leads inexorably to Barack Obama.
