DD says that several of her friends are doing this on social media.
I've also heard it in person from two girls in two different classes who have made comments in front of me about how either their parents or their friends parents are horrible homophobic transphobic people. When questioned they double down and say things like "well my friend came out to her parents and they weren't supportive of her going to Pride" (this was from a 13 year old!)
Another girls mum who is an old friend of mine said to me that her dd does it all the time about other kids parents and that she suspects this child is also saying it about them.
The child is - the child has been at our house saying it and when I said "you realise that your mum has loads of gay friends don't you?" The child basically looked a bit blank and went red and mumbled into her Doritos.
Apparently next day in class she was at it again. In front of teachers!
DD says one of the latest things on TikTok is to complain about parents being phobic - massive oppression points for middle class kids!
