I would say it doesn't matter.
Because introducing trans identity to children in school isn't about changing society. It isn't about making people more or less tolerat (I mean, we hope it helps, but that's not the main point).
It's about making sure the next me, the next Sophie, the next Emzie, the next Igloo isn't left to suffer in ignorance like we were (often gaining lifelong scars in the process). It's about giving them the words and the tools to understand themselves, and be happy at an age when we couldn't be.
And that's precisely why teaching kids about being trans inflame the conservatives so much.
