A Maryland school district can order a substitute teacher to use a student’s chosen pronouns and, according to the same policy, forbid her from telling that student’s parents. If Montgomery County’s guidelines were a curriculum requirement, this would not be a close case. The Supreme Court has told this district once already that keeping parents in the dark on this subject crosses a constitutional line. That’s a strong bench of precedent pointing the same direction, and it’s worth asking why the Fourth Circuit didn’t feel the pull of it. That distinction is exactly why the Supreme Court should take this case.
