Marches, rallies and honks for peace are all good strategies — but they're not enough, say local activists who gathered Saturday to discuss tactics for social change. It's time now for something more, a kind of "peaceful uprising," they say.

The all-day conference at the University of Utah drew about 150 activists representing groups ranging from the Healthy Planet Mobilization Committee to a new group called Provo for Palestine. There were environmentalists, peace activists and union organizers. Panelists included former Salt Lake City Mayor Rocky Anderson and Tim DeChristopher, the eco-saboteur who last month disrupted the Bureau of Land Management auction of oil drilling leases.

The "old model" of social activism hasn't proved effective, said DeChristopher, who appeared on two panels. "We have to convince leaders that there will be an uprising," he said. "Changing a light bulb is not an appropriate response" to the climate crisis.

After a day of panels and films, about 30 people attended the final, what-shall-we-do-now session, where they discussed their shared vision of a "just, sustainable and peaceful world" and the pros and cons of getting arrested for their causes. Sixteen of the 30 raised their hands "yes" when asked by attendee Caleb Proulx whether they would engage in that level of civil disobedience.

"Sometimes you're willing to do whatever it takes, and maybe that time is now," said longtime peace activist Diana Lee Hirschi, who was arrested in 1989 as part of a national campaign to stop production of the Trident missile system.

While marches and rallies are helpful, "we could do something that's creative and powerful," suggested Ashley Sanders, who helped organize the "alternative commencement" at BYU in 2007 to protest the traditional commencement address of Vice President Dick Cheney and was youth coordinator for Ralph Nader's 2008 presidential campaign.

Sanders suggested an "action" near the end of this year's legislative session. "We'll descend on the Capitol and hold an Athenian people's legislature," she said. She envisioned thousands of Utahns, perhaps wearing togas, frustrated by the laws being passed by the lawmakers and calling instead for ethics reform and clean air. She also pushed for civil disobedience, with the protesters asking for their own bills to be passed "or we're not leaving."

"That's a recipe for martyrdom," countered peace activist Dayne Goodwin, who drew the line at actions leading to arrests.
