So how does the country as a whole decide?
I've tried actually to rationally discuss this with you, but it seems you'd like to ride a unicorn over yon rainbow to chase what should be instead of talking about this rationally in terms of what is practicable.
The nation should decide? fine, then tell this teacher to stfu until it does.
Well, I actually said this.
Either through politicians making the decision. You know, we elect them do make such decisions.
Or by having people take a vote in a referendum.
Or by following the Constitution and saying that all people should be treated equally, and they can do what they like as long as they don't hurt people, and teaching this sort of thing. You know the people have legitimized the Constitution for a long time now.
As for your unicorn comments, well.....
You seem to think rational arguments are me agreeing with you. Er... doesn't work like that.
At present primary school teachers have a lot of leeway in what they can teach.
Should a teacher only teach things they've been specifically authorized to teach?
So if a kid can't do his shoelaces up, but the teacher hasn't been authorized to teach them that, then they have to tell the kid they can't teach it to them?
Sounds ridiculous, doesn't it?
Why shouldn't a teacher tell kids about their own family?
