More than half of U.S. state school boards have pushed back against the National School Boards Association (NSBA) after the organization sent a letter to the White House suggesting parents might be engaging in domestic terrorism.

More specifically, 10 state school boards have issued statements disagreeing with the letter, and 17 more state school boards have either voted to withdraw their memberships, participation and/or dues from the NSBA, with Georgia, Florida and Alabama being the most recent examples, according to a list from school choice organization Parents Defending Education (PDE).

“Labeling parents as domestic terrorists isn’t a great strategy when it comes to your organization, whether you’re a school board or any other type of organization,” school choice advocate Corey DeAngelis told Fox News of the movement against the NSBA.
