(JTA) – Graffiti including swastikas was painted on the walls of a San Francisco-area high school. Days after the incident, hundreds of students came to Burlingame High School wearing red T-shirts or hoodies in red, a school color, to display “unity against hate.” They placed their painted handprints on banners reading “We are stronger than hate” and “Panther strong.” The principal, Paul Belzer, described the graffiti painted in 10 different places as “antisemitic, homophobic and racist.” He said an investigation by the Burlingame Police Department and the San Mateo Union High School District is underway. No suspects have been identified. “I am outraged,” Belzer wrote in an email to parents. “I feel our students and school, and our school’s values of integrity and community have been attacked.” There have been other such recent incidents at the school and at intermediate and elementary schools in Burlingame.
