Alex Callinicos, a professor of European Studies at Kings College in London, announced to his rapt audience, “I am a Marxist.’’

Asked if the upcoming revolution can be non-violent, he parroted the party line of the demonstrators, who call themselves the 99 percent of Americans lined up against the “1 percent’’ with power and money.

He said violence could be avoided only if the “1 percent accept the decisions of the 99 percent,’’ which he predicted would never happen.
