The new guidelines seem to promote "a specific viewpoint aimed at achieving cultural and social transformation in schools" just as much as the 2021 model. The 2021 model policies at least prioritize the well-being of the students with whom teachers and school staff interact every day. Many of the policies are common-sense and strive to be inclusive of all students, even if they could go too far in some cases.
For example, being called by their preferred name and pronouns is very important to transgender students, and that is a simple way to support the students as people. On the other hand, it can be difficult to teach an old dog new tricks, so teachers and staff should not be punished for the inevitable mistake. Outright refusal by teachers can only harm the child's education by creating an oppositional relationship where there was an opportunity to build trust.
Also, single-sex bathrooms should be limited to those born as a given biological sex, but single-user and/or non-gendered bathrooms are a reasonable solution.
The most concerning part of the new model policies is the assumption that the old policies "[require] individuals to adhere to or adopt a particular ideological belief" or "[compel] speech that is contrary to an individual’s personal or religious beliefs." There is a clear difference between being compelled to believe something oneself and supporting a student in whatever difficulties they face. Being compassionate does not require adopting the other person's ideology or abandoning one's religion. I can't imagine a teacher would refuse to engage with a student who is struggling with parental divorce or suicidal ideations on the grounds of religion or personal belief. One would seem to be terribly fragile if they could not work for the good of all students. If a teacher's beliefs are so entrenched that they can't offer struggling children a little empathy, perhaps they need to teach at a religious school. (And those schools should not be funded with public dollars. They can teach what they want, but they should pay for it themselves.)
The new model also emphasizes parental rights. Certainly, parents should be free to raise their children as they see fit within the law. But the unfortunate fact is that many parents are unable or unwilling to support their children as well as the children deserve, and so schools are forced to take on roles beyond education. Other students may not be comfortable telling their parents about struggles with gender identity. Teachers and other school employees might be the only trusted adults these students can go to. However, it seems like the new proposal will discourage students from using that opportunity, which will lead to worse outcomes for their health and personal development as well as their education.
