Many of them have been anywhere from insulted to assaulted for entering women's bathrooms.
I expect you have lots of links to back up this statement.
I assume this is in the US. We don't have public bathrooms in the UK. But I also assume this has got much worse in recent years since some male people have insisted that their self-declared 'gender identity' (feeling womanly in their heads) means that they should access women's spaces.
A trans child.
What is a trans child?
The Tavistock followed the medical path she chose to have and I'd definitely look into the dangers of insisting young women are incapable of making their own medical decisions, as Bell's case is currently being used by anti-vaxx and anti-abortion activists.
The Tavistock affirmed her self-declared trans identity rather than investigating why she believed she should be a boy. This was negligence on their part. At 16 she was still a child.
A girl who has gone through puberty and is pregnant is capable of understanding what is happening to her and making decisions about what she wants to do.
A child is not capable of making a decision to be sterilised and have treatment which will leave them with impaired sexual function.
Go ahead and fight for the right to sterilise children. I'll still be fighting against it.
