I saw a lot of push and propaganda in schools to subvert this setup, for my kids in the name of ideology. This is now the #1 issue for me to push back on. Just a single data point.
edit, responding to below:
By "heavy advertising" do you mean letting kids know it is a thing that exists? Because that's just teaching kids the facts of life, something schools have a responsibility to do (since apparently you're not willing to tell your kids that medical transition exists?) It falls under the same bucket as sex education, another thing that schools should do regardless of whether the parents think it's OK or not.
Schools don't make medical decisions, doctors do.
edit 2:
MEDICAL transition.
Relevant quote:
===
Even though the policy states that “the goal in all cases is to strive for consensus between parents/guardians and student as to the application of this policy,” it adds that the decision to participate in the “gender transition plan” belongs to the student, and “does not require additional parent/guardian consent”—unless parental/guardian rights under the Family Educational Rights and Privacy Act (FERPA), or other applicable law, would be implicated.

"Schools transitioning children" is not a coherent phrase. "Transition" in the gender sense is not a transitive verb; transition is not something done to someone by others, is something that person does themselves.
