California Gov. Gavin Newsom signed a bill Monday to ban school boards from rejecting textbooks based on their teachings about the contributions of people from different racial backgrounds, sexual orientations and gender identities.
Newsom called the measure “long overdue.”
“From Temecula to Tallahassee, fringe ideologues across the country are attempting to whitewash history and ban books from schools,” Newsom said in a statement. “With this new law, we’re cementing California’s role as the true freedom state: a place where families — not political fanatics — have the freedom to decide what’s right for them.”
The bill takes effect immediately. The topic of banning and censoring books has become a U.S. political flashpoint, cropping up in states around the country. Many of the new restrictions enacted by conservative-dominated school boards have been over textbook representations of sexuality and LGBTQ+ history.
The California bill garnered heightened attention when a Southern California school board this summer rejected a social studies curriculum for elementary students that had supplementary material teaching about Harvey Milk, who was a San Francisco politician and gay rights advocate.
A 2011 state law requires schools to teach students about the historical contributions of gay, bisexual and transgender Americans. Newsom threatened the school board with a $1.5 million fine and the board later voted to approve a modified curriculum for elementary students that met state requirements.
