Groups such as the PTA, local principals and the city's Community Coalition spoke in support. Out of the 17 speakers, 13 were in favor.
Opponents included students and resident Bruce Hopping, who cited the failures of Prohibition.
LBHS sophomore Andrew Landsiedel, the son of school board member William Landsiedel, started a Facebook group dedicated to the issue last week because he felt all perspectives weren't being heard.
"Have kids work with police instead of two warring groups," Landsiedel, 16, said. "This sort of law would just move the parties to beaches and parks, where kids could potentially hurt themselves."
Andrew believes the most troublesome parties have happened in Emerald Bay, outside the Laguna Beach city limits. He thinks the ordinance would teach kids to fear the Police Department, which he says regularly enforces curfew.
As of Wednesday, 685 people joined the group, which is comprised of fellow LBHS students, parents and local supporters. The page includes research that the students compiled, posts of support and Benjamin Franklin quotations extolling liberty.
The group of organizers — which includes Andrew, junior Schuyler Vanderveen and seniors Adam Redding-Kaufman and Macklin Thornton — plan to speak at every council meeting that has the ordinance on its agenda. They have a protest planned for the May 15 meeting.
They also asked students to dress in suits and ties Thursday during a high school demonstration to show the council that they want to be taken seriously. However, late Wednesday night, an on-campus protest was called off, but no reason was given.
