Once again young people are in revolt, from Indiana and Florida to New York and California.

Teenagers and 20-something-year-old activists are finding friends and allies among the baby boomers who are now in their sixties, and who once demonstrated against the war in Vietnam, racial injustice and patriarchal authority.

The boomer insurgents are not going gently into old age and retirement, though many of the protesters at Columbia in 1968, including Tom Hayden, Abbie Hoffman, Robert Kramer, John Jacobs, Barry Willdorf and Gus Reichbach are no longer alive. Melvin Margolis and Lynn Phillips, two young radicals who filmed and edited the 1968 Newsreel documentary “The Columbia Revolt,” died shortly before the 50^th anniversary of their work and the protests they memorialized.
