The debate surrounding this policy seems to be focused on a fear of what harmful things parents might do to a child who is questioning their gender. It seems like most people who oppose this policy are assuming that parents will be abusive towards their own children in some way. I believe most parents have good intentions and want what they believe is best for their kids. In response to someone who opposes this policy I would ask them, "If we cannot trust parents to raise their own children in a loving way, then who can we trust?" Personally, I do not believe parental involvement is inherently harmful to young developing children. I believe every parent should have the constitutional right to teach their own child what they want them to believe in regards to sex, gender, and identify. It is not the responsibility of a school or teacher to take a stance on this issue and teach their opinion to the students.
As a solution:
I think teachers should give any student who wants to change their name, pronouns, or gender identity a permission slip. This slip would require a signature from a parent or guardian just like they would use for any field trip. The student would be able to make the choice for themselves if they want to involve their parent in this matter by giving them the form. If the student feels they can trust their parent enough to give them the form then the parents involvement in the matter shouldn't be an issue, and any student who does not feel safe with their parent involved would have the opportunity to not go through with it because they are not yet ready for such a big change in their school life or their home life. If this is a change that the child intends to make the parents are likely to find out eventually and unnecessarily hiding this important information from the parents would only make things more secretive, more fearful, and more problematic later on in the childs life.
In conclusion, parental involvement would be a good thing because it would promote honesty and open communication in the home. We need students and parents to communicate with one another in order to reach a solution on these issues.
