I have hope that although very few of them will come out and say it public yet, for fear of upsetting their friends or getting piled on, more young people are seeing through the trans ideology.
DD (17) is bi, hangs out with an arty, social-justice-focused crowd with multi-coloured hair and interesting piercings, and a large proportion of her friends are somewhere on the LGBTQ+ whatever spectrum, including several who identify as trans/non-binary. You would expect her to be totally "TWAW, mum is a terf", right?
But she read the JKR piece and agreed with her, and has been having undercover chats with several of her gay/trans friends over the past few months, who also broadly agree that sex is a real thing and a lot of people currently identifying as trans/non-binary are caught up in a fashion. Her gay friends don't dare say it in front of their trans friends, for example, but even teenage gay guys are absolutely not interested in trans men. A gay friend of hers said this week how glad he was that his parents did not hear about 'trans kids' when he was little, and was starting to show his interest in 'feminine' things. He is very happy being a gay man with a fully functioning penis, rather than spending years on puberty blockers.
Within the last few weeks at least two girls she knows who have identified as boys for two or three years have decided they are actually girls after all (another friend was only trans for about a year, aged 14).
And DD can clearly see how Tumblr and youtube have worked to convince girls who don't fit in with female stereotypes that they are actually boys.
