Homeschool your kids if you have any doubt about what the school is doing with them. I'm a teacher and I would hate to see public schools shut down. They are worth salavaging, because they used to be something our nation took great and rightful pride in. Even if you're not a public school parent anymore, you are still a public school taxpayer and a public school voter for school boards.
Don't give up on the idea of public education.
That said . . . I believe that the overwhelming majority of teachers have no interest in grooming or transgenderizing children. But too many counselors don't realize what grooming and transgenderizing is. They are reading the literature from their professional organizations that is telling them that they need to "be aware" that children may have gender confusion and not talk about it for various reasons, including the usual suspects of bigoted parents.
Combine that with children being force fed books and other materials that make suffering heroes of kids who come out as transgender, and you have the perfect storm that will induce counselors to look for and find transgenders among kids with depression and autism spectrum disorders, two conditions that are very, very frequently co-morbid with gender dysphoria.
You don't have to leave your kids in public school to fight to change public school. Nor do you have to let public schools do as they please if you do keep your child in public school.
