OAKLAND, Calif. – Officials at Oakland’s Claremont Middle School are helping students organize protests against President-elect Donald Trump unbeknownst to their parents, essentially endorsing the disobedience.

About 300 sixth, seventh, and eighth-grade students walked out of class Thursday as part of an anti-Donald Trump protest organized on Instagram. Teachers and school officials escorted students around the Rockridge neighborhood while they chanted and waved signs with Hillary Clinton campaign logos that read “We have the right to protest” for the first two class periods of the day, NBC Bay Area reports.

Teacher Lacy Lefkowitz told the news site students are petrified about the potential ramifications of Donald Trump’s historic victory Tuesday.

“They’re concerned about racism, the wall Trump wants to build and immigration,” Lefkowitz said. “It’s not OK to loot and set fires. But I think this is a great thing for them to do.”

Principal Jonathan Mayer approved the protest, and did not inform parents their children left the school grounds until after it was over.

Mayer sent a recorded phone message to parents around 9:30 a.m. to let them know “at all times we had teachers and adult supervisors” who made sure “no one went into the street,” NBC Bay Area reports.

“We support students’ rights to express themselves,” he said in the message. “We encourage them to take their political activism to act with friends and make a difference.”

The walkout at Claremont Middle School was part of a much larger backlash to the election results from students across the region in recent days. Protests in many Bay areas resulted in severe damage to businesses from rioters and looters.

The Bay Area News Group reports:

Beginning with UC Berkeley students Tuesday night and continuing Wednesday and Thursday, thousands of students from both urban and suburban high schools have flooded the streets, pouring out of classes carrying signs and flags, chanting and singing and beating drums to demonstrate their indignation with Trump’s election.

In San Jose, students on Thursday channeled their anger and fear over Trump’s victory into a march on City Hall, where about 400 students from at least five high schools marched en masse, shouting “Trump is not our president” and “el pueblo unido jama sera vencido” — the people united will never be defeated. …

Across Contra Costa County, students protested in droves. Roughly 1,000 students walked out of four high schools in Richmond, where approximately 80 percent to 90 percent of the student body is Hispanic and the stress level is high, said Jose de Leon, Richmond High’s principal. …

They joined fellow high school students in Concord, Pleasant Hill, Antioch and Pittsburg, where three boys were arrested during a walkout that included several hundred students.

And, in Oakland, students from Arise High School invaded a news conference hosted by Mayor Libby Schaaf and council members Abel Guillen and Lynette Gibson McElhaney, where the elected officials urged demonstrators to spare local businesses the vandalism that occurred Tuesday and Wednesday nights. Students from Envision Academy for Arts and Technology, Claremont Middle School, and Madison Park Academy, a school for students from sixth to 12th grade, also walked out on Thursday in protest.

In many cases, students are simply following the example of adults at their schools.

Phil Morales, principal of Santa Clara County’s Milpitas High School, was put on leave for anti-Trump profanity during a student walkout Thursday, and many educators have vowed to “fight” for minority students, who are allegedly terrified about life with President Trump.

“I am a teacher of 100 percent black and brown students who are experiencing psychological terror right now,” north Oakland teacher Katie Kelly-Hankin told the Bay Area News Group. “I have to tell them that what I’m going to do is stand up and fight and that they have the power to do that, too, and I’m not going to stop fighting.”
