I can't see a definition of gender identity in your 'answer'.
You've waffled on about not banning talking about gender identity in school. I never said talking about gender identity should be banned.
You've also waffled on about how you'd go about teaching about gender identity. I didn't ask about how you would teach about it.
I asked you specifically how you define 'gender identity'. You haven't done this.
The other question was why do you think teaching about it is so important? Not how you'd teach it, or why you think banning it would be bad, but why do you think children need to learn about gender identity? What are the benefits to children of learning about gender identity in school, other than "it's better than learning about it on tiktok"?
Personally, I don't see why they shouldn't just get their information about a meaningless concept from whatever source they want. Why is it important that they learn about it in school? Why not just get their information from tiktok, seeing as gender identity is a meaningless concept?
But first you need to answer the first question: What do you mean by 'gender identity'? What does 'gender identity' mean to you? Why is it important to you? Explain it to someone who hasn't ever heard of a gender identity.
I hope my questions are clearer now.
