Finally read the linked post, and am laughing (with you as much as at you, Charlotte, if you're reading) because I can remember the life stage where I'd have written very much like that. Except that in my case it was Marxism that I loved to lecture people about. My poor, long suffering working class family who had to listen to far better off than them at the same age teenage me bang on about seizing the means of production. I should send them a hamper to apologize.
Due to the fact that I go to a fairly progressive girls’ school and have friends from all over the gender spectrum
Translation - I'm middle to upper middle class and a bit smug about it, allow me to use my relative privilege to explain these issues to the lumpenproletariat.
How is this suitable behaviour from a group of parents?
If you're a mother then you're everyone's mother! Now act like a loving, indulgent mummy or I'll sneer at you a bit more for being old and thus obviously not with it enough to understand things the way I do.
Like Lang said earlier, I'm certain that I was probably just as smug and annoying when I was a teenager, and I'm glad that no public record exists of that life stage for me. This generation of kids are going to be so embarrassed when they look back at the stuff they put online as adolescents when they're older. At least back when people wrote it in their diary instead the cringe was limited to the one person who found it buried in a box of old stuff later.
I kind of get what some people are saying about going easy on the kid because she is a kid, but at the same time looking back on myself at the same age I'm glad people didn't do that because it would just have prolonged the learning how to engage with the world appropriately and effectively process. I've seen what happens when kids are insulated from that until they're well into their university years, and it's not good.
The combination of incomplete cognitive development and lack of life experience makes it unsurprising that a lot of teenagers don't quite understand why self-ID is such a threat. They may not like our stepping in to preserve their rights for them or understand why we're doing so, but it's still our responsibility as adults to do it. Teenagers have always railed against their elders - it's a life stage, twas ever thus, etc.
