I am 20% into Irreversible Damage and am horrified. I feel sick reading a lot of it. Trans influencers and social media have a lot to answer for. Some trans influencers say that if you wonder if you're trans then you probably are and there's nothing wrong with just trying the hormones. In California, kids 12+ are allowed to leave school to go and get hormone treatments without their parents being informed. Teachers will also call them by whatever name/pronouns they want without asking parents. Studies are showing that young females are less likely to come out as gay and instead trans "cause if you like the same sex then you're a boy." it also talks about how often anyone who is now a tomboy or a feminine boy is labeled "non binary" by peers or teachers.
Kids in California are taught about gender/trans/pronouns from kindergarten. They have people come in and do talks about it. Kids brains and sponges and they are literally being indoctrinated to this
Abigail Shrier says most people who really have gender dysphoria present signs from a young child. What they are seeing now is teens saying they are trans that have never shown any signs as a child.
