Your foundation for these policies is wrong. Your terminology is different than my understanding of those same words.
Children must not be encouraged to "try on" a different anatomy!! "Gender" and "anatomical features at birth" are one and the same! Socially accepted views of female and male "activities" is a completely different thing from "gender".
As a parent, i want to encourage my child to learn to do things in life that they enjoy while accepting who they are, not try to change who they are! Don't push the opposite into the schools!
How can my child accept who he is of you're out telling everyone that if he doesn't like his p3nis, he should get surgery and get a lab1a?!
