Part of education, especially childhood education, has to be teaching children about the world they live in and how to navigate it. Which does mean that they need to be taught about tolerance and the differences between people. That's necessary for understanding and navigating the world they're entering. And teachers are there to guide them on that journey and keep them safe. To be an adult to whom they can ask questions without fear of reprisal. To be someone primarily interested in their success and not some other political goal.
Conservatives are the ones stepping into this process and interfering. Forbidding teachers to teach about the world. And forcing teachers to violate the confidence needed to keep children safe. Conservatives are the ones trying to replace education with a tool for indoctrination.
The only interpretation of a rule like the one in this article is that there is a belief that a child questioning their gender is equivalent to a child admitting to some kind of self-harm. It's pure bigotry and cruelty from people who know nothing and resist learning anything about the science and psychology of the subject. It is part of a genocidal agenda of demonizing and denying part of human identity. It is unacceptable. And worse, it's a violation of the fundamental relationship between the teacher and the student. It's interfering with and taking focus from education.
