Do you have more of this story? I don't think I've heard this particular one. Absolutely heartbreaking, glad to see the girl appears to be recovering.
I've not followed it that closely, but from what I know, an autistic teenage girl (Anna) decided she was trans, but her mom (Brette) - clearly not a believer in troon bullshit - felt that she had been coaxed into believing that by other troons.
After some time, Anna desisted, leading to her getting bullied and sent death threats by other troons at her school who had once been friends with her. The old "apostates must suffer" shit. Brette complained to the school, who basically did nothing.
Brette tweeted out their story, leading to a bunch of harassment heading her and Anna's way ever since. Troons and TRAs have reported Brette and her husband to CPS and falsely accused Anna of distributing child porn and being a sexual predator. The troons/TRAs believe that Anna is a "trans child" who is being made to look/dress a certain way by her TERF mom, which obviously makes them insane with rage.
In March this year, this account was created on Twitter, which posted 2 topless photos of Anna taken when she was 16: -
The account was banned, but another account was created and the photos were posted again, then that account was also banned.
Brette claims that Anna was coerced into sending the photos by someone who was intent on using them as revenge porn and she reported it to the police. This is supposedly a copy of her witness statement, posted to Twitter by Brette herself: -
That's about all I know.
