China's Great Wall of Silence: American Complicity

Here is a Maoist website based in the United States that glorifies the Red Guard murderers and the entire Chinese Holocaust that was the Cultural Revolution. Last year they had a convention in the Pacific Northwest where they proclaimed the C.R. the greatest movement in mankind's history. I am told that the webmaster is a professor at Duke university.

Why doesn't Google shut this site down?
Why doesn't the U.S. government label this organization what it is, a terrorist group?
