Here is an outstanding video exposing the "Agitprop" used by Democrats and the Liberal Media to try and discredit those who protested against passage of ObamaCare.
The early Soviets coined the word "agitprop" as a blend between the Russian agitatsiya (agitation) and "propaganda." That's the tactic used in accusing protesters at the U.S. Capitol on March 21 of shouting the "N" word at Black Congressmen, and of "spitting" on Missouri Democrat Rep. Emmanuel Cleaver.
The video points out that the group of Black Congressmen could have used the "tunnel" to walk from their offices to the Capitol, which would have been customary. Instead, they chose as a group to walk through the protesters in dramatic fashion.
