I am not aware of bullying causing gender disphoria.
Generally it causes weapons, and a level of violence escalation that ends badly.
Gender disphoria is generally caused either by having no role models, by having a high level of hate for the parent or guardian of the same sex, or its inculcated by a family that treats a child as being the opposite sex from what they are.
I was informing you that bullying is alive and common today despite media and academic insistence that it is a thing of the past. Not asserting thay being assaulted causes gender disphoria.
I have known a number of people with intersex conditions. Even with people who have a physical ambiguity as to their sex gender disphoria is hardly ubiquitous.
From the article it sounds like this kid’s mother lead him to pretend to have gender disphoria. Instead of like...getting him a big dog that would have bitten any bullies hanging round.
Actually a big percent is caused by extreme childhood trauma, especially sexual abuse. They need counseling for being abused as children, not more abuse in the form of gender surgery.
Candace Owens interviews Walt Heyer who did have that operation and then a reversal, and has done many studies of the issue, its causes, and leads a large organization in opposition this terrible process and seeks to help those who regret what they have done. He is speaking out to raise awareness that those who do this have other serious mental issues and this operation will not help them, but make them worse. Not a popular platform in todays upside down world.
