Another Obama banner features Communism's red star
When Bill Ayers was cornered by a Fox News reporter he was wearing a shirt featuring the red star.
The red star is the universal symbol of communism, said to represent the "five social groups that would lead Russia to communism: the youth, the military, the industrial labourers, the agricultural workers or peasantry, and the intelligentsia."
The Russian military uses the red star to this day. Nothing to see here folks, just move along.
