She's too coy in her wording and too consistent in her platforming of, and rubbing shoulders with, people who explicitly hate us — and don't shy away from saying as much — for me to lend any benefit to her being genuine when she says she loves trans people. If she had lunch with me she wouldn't take me as one of the good ones because I'd have no trouble telling her to her face what her actions have resulted in.
If a children's charity writes an open letter to you letting you know your actions have resulted in trans children attempting suicide, and your response is to campaign against them to the point where they're having to limit vital services then I struggle to believe you're someone who thinks you love trans people. This isn't the process of a person whose foremost thought on us is compassion.
I really don't see the point in giving concessions to Rowling. She knows what she's doing and she's deliberate in doing it. She's found a means of being openly bigoted that results in her being heralded as a champion of women's rights by the media apparatus of an entire country. Trans women being the enemy is the key element sustaining that glory. There's zero reason to believe she thinks she's genuine when she claims to care about trans people, when she's deliberately doing what she can to make our lives worse and has been doing so for years.

Kyuji is such a fucking snake.
Mermaids made a claim that not doing whatever teenagers state they want guarantees they will kill themselves, which is transparently
horseshit.
Self-serving horseshit at that. It doesn't merit a fucking response, there is literally no foundation of evidence for that to be true in any sphere, whether thats gender identity or just wanting to do drugs and alcohol.
Her 'campaign' against them amounted to
exposing what they were actually fucking doing under the guise of charity work.
Having to 'limit' vital services due to being overwhelmed by public vitriol was NOTHING to do with anything JKR said.
IT WAS BECAUSE A PRESS INVESTIGATION REVEALED THEY HAD A PAEDOPHILE AS A HIGH RANKING MEMBER OF THEIR EXECUTIVE BOARDWEIRDLY as a fucking CHARITY DEALING WITH VULNERABLE CHILDREN there was a lot of public backlash!
