Maybe it was the suddenness, that 44 names were being deleted all at once. Or maybe it was the feeling by many that the Board of Education had gone one step too far, and during a wrenching pandemic to boot. Whatever the reasons, the decision to wipe out one-third of the city’s school names, including ones honoring Washington, Jefferson and Lincoln, has struck a nerve in San Francisco.Less than 12 hours after the city’s Board of Education voted to change the names, Mayor London Breed lashed out at the decision, questioning the board’s priorities. “Let’s bring the same urgency and focus on getting our kids back in the classroom, and then we can have that longer conversation about the future of school names,” Ms. Breed said.
