You seem unable ever to judge any comment of mine as just generally applicable to a thread and insist it must be about you. It says something about you.
Is that to me? When you quote me and reply, it's reasonable to assume you mean me - otherwise you use the passive aggressive 'Some People'. I'm not sure what that says about me, but it is obviously a personal dig.
I was teaching in the 80s and well remember Section 28 (if that comment was meant for me). I know for a fact that others on the thread were also working in education then, and it was often in the News at the time, so I don't know why you think we all need the benefit of lectures about the past. They have nothing to do with now. Can you explain what discriminating against people on the grounds of sexuality, whether in the 70s, the 80s or the 2020s has to do with any of this? The teacher concerned is not, AFAWK, gay. He 'identifies' as male, so presumably is not trans either.
My objection is to children getting mixed messages about what it means to be male and female, eg by being exposed to drag queens in sexualised outfits at a young age in the name of 'inclusivity', by being told that there are multiple genders to choose from, that men can become women etc, and that these messages include notions of being in the 'wrong body' and 'changing gender'. I worry for their safety, as if they learn to mistrust the evidence of their eyes, they could put themselves at risk. If we opened up societal assumptions about 'gender' roles why would children want to 'transition' instead of just behaving as they wish when it comes to these roles?
Having more choices would help adults who are not gender conforming too, including the teacher in question. Remove the rest of the pieces of the jigsaw and I would feel as would if the teacher wore his skirt in the pub - ie neutral. But when children are being told about being in the 'wrong body', have new pronouns affirmed and generally expected to make a choice about their identity on sex, rather than 'gender' grounds, it feels like a step too far. They are children. Why not learn societal norms at this stage, so they can choose to ignore them later, much as they need to learn the notes in music and basic rules of grammar before they can decide when it is better to freewheel.
