Like many other Americans, I have been impressed with the poise, passion and guts of the Florida teenagers who survived the latest big school shooting, as well as that of their student allies in other cities who walked out of class, took to the streets and/or confronted government officials to demand that they take meaningful action to reduce gun violence. As we mark a series of big 50th anniversaries of the cluster of dramatic events that took place in 1968, one wonders: does this augur a return to the street-level militancy of that tumultuous year?

The '60s were the decade of youth, an era that ended when baby boomers aged out of flowers and free love into jobs and suburbs. Adulthood makes everyone put away childish things — not that agitating against war and fighting for equal rights is kid stuff — and to be fair to the boomers, they were driven off the protest lines by hails of government bullets at places like Kent State University. For my money the '60s died in 1972, the first year 18- to 20-year-olds got the vote and either didn't show up or used their new franchise to re-elect Richard Nixon.

Compared to the heyday of the anti-Vietnam War movement, when every little town in America had protests pretty much every day for years on end, the activist left has been on hiatus ever since. There were Solidarity Day in 1981 and the Battle of Seattle in 1999 and marches against the Iraq War in 2003 and Occupy Wall Street in 2011 and, recently, a pair of anti-Trump Women's Marches. But those events were intermittent, exceptional, spasmodic. Generation X — discriminated against, passed over for good jobs, marginalized by culture and media — was too busy working multiple crappy jobs to organize, protest and effect change.
