Oh good lord Dita it's not about a few 'bad people' merely exploiting a system. It's about a law that obliterates safeguarding, grooms the public into an acceptance they don't feel, and gives every paedophile and predator access.
There are far, far more predators taking advantage of a law that was designed to alleviate the symptoms of gender dysphoria, then there are men who have gender dysphoria.
In Canada, where they are ahead of us in terms of self ID:
I take notice of the fact that transgender and gender non‐conforming persons face high levels of stigma and are at an increased risk of violence, harassment, social isolation and discrimination. In these circumstances, I am satisfied that it is better to err on the side of caution in protecting a transgender person who asserts that the publication of their name in association with a complaint may expose them to harm. Doing so on an interim basis had minimal, if any, impact on the integrity of the Tribunal’s process.
This was written about a man who asks anyone who will listen how he can help 10-year-olds insert their tampons. They have decided to not publish his identification. Despite dozens of young girls identifying him online. Because he's claiming to be trans.
Which protects him more than someone who is not trans.
Why? Why does it?
