Across the U.S., lawmakers in at least 28 states are attempting to pass so-called anti-critical race theory legislation that would prohibit teachers from teaching students about the role of racism, sexism and oppression throughout U.S. history.

In response, educators across the United States are signing a “pledge to teach the truth.” And this weekend, educators in at least 115 cities will stage public demonstrations to stand in protest against the wave of bans on discussing social justice issues in American schools and workplaces.
