They've seen trans and nb kids being endlessly pandered to at school
I mean you said it, here.
I'm very, very glad that your kids are too sensible for this harmful nonsense but they have no power or influence. They won't have any power or influence over the world of education for a very long time, if ever (in all likelihood depending on their career path etc). I'm sorry if that sounds harsh. And they aren't in agreement with the majority of teens either, at least not as yet.
Meanwhile more and more teachers are turning towards this ideology and becoming convinced of it, the ones who simply weren't aware of it before, including experienced leadership staff. We are all getting "trained" on it. New teachers getting trained in teaching with this brand of EDI interwoven into all their practice. Diehard converts getting promoted into senior roles.
