"Tension is not always bad," Hewitt told the Guardian at the event. "Everybody came here with biases and interests. Everybody needs to leave here with more. I'm damn near 60 years old and I grew half an inch today."

Sunday's congress and policy platform were modeled after San Francisco's first Community Congress, which took place in 1975. But Welch told us this congress was entirely new. "To the extent that there is a historical aspect, 35 years ago we tried to figure out a way to bring people together. And 35 years later, young people want to do the same thing."

"Diamond" Dave Whittaker, a modern Emperor Norton-esque San Francisco personality, closed the congress with a poem. "The basis of real social change is happening here," he said. "And we need to continue casting a wider net, finding the thread, and letting it flourish."
