Following the National School Boards Association letter sent to the White House comparing parents to domestic terrorists, the nation’s largest teachers union sent a letter to social media companies encouraging them to crack down on “propaganda” surrounding Critical Race Theory (CRT) and other education concerns raised by parents.

National Education Association (NEA) president Becky Pringle requested “the leaders of Facebook, Twitter, and TikTok to prioritize the safety of people over profits,” according to the letter. She said the speed and reach of lies on social media are “manipulating” citizens in a way that wouldn’t be possible if their platforms didn’t exist and called on the companies to make a pledge to fix their algorithms to “regulate lies.”

There is “alarming growth of a small but violent group of radicalized adults who falsely believe that graduate level courses about racism are being taught in K-12 public schools because of misinformation spread on social media,” the letter said. “And there are another small yet vocal group of extremists who are putting the safety of our children, educators, and families at risk over the notion that wearing a mask is in infringement on personal liberty.”

Despite NEA claims that there are unfounded beliefs regarding “graduate level courses about racism,” in U.S. public schools, the union approved a plan to implement CRT in 14,000 school districts across all 50 states in July.
