San Francisco's public schools have been offered a classroom lesson plan that calls President-elect Donald Trump a racist, sexist man who became president "by pandering to a huge racist and sexist base".
The union that represents city teachers posted the plan on its website and distributed it via an email newsletter to its more than 6,000 members. The school district has more than 57,000 students.
It is unclear how many teachers have used the plan outlined by a Mission High School teacher, but it appears to have the tacit support of city education officials.
School district spokeswoman Gentle Blythe said the plan is optional and not part of the official curriculum.
"Educators are entrusted to create lessons that reflect the California standards, support students' social and emotional well-being and foster inclusive and safe school communities," she said in a statement that neither praised nor rebuked the lesson plan.
San Francisco schools serve diverse populations and teachers are encouraged to include multiple perspectives in lessons, she said.
The Republican Party in San Francisco reacted sharply. "It's inappropriate on every level," said Harmeet Dhillon, an RNC committeewoman from California. She called it "inappropriate propaganda that unfairly demonizes not only the campaign that Donald Trump, the winner, ran, but also all of the people who voted for him."
