I would do it if they wanted to be ‘they’
I have 2 teenage girls and I have brought them up alone with a minimal Male influence, I have always been very open that girls/women do not have to fit into a stereotype of any kind, there has been no pressure from me.
They go to mixed schools that have optional skirts as part of the uniform and partake in mixed sex PE lessons.
I have asked them what they would think of a transgender girl using their changing room and they said as they would know them ie not a stranger, and no one is naked in front of each other, they are not sure they would feel it was harming their rights and would also want the other person not to feel uncomfortable but accept that it is probably safer in a girls space than a boys for a trans girl. They already know this
They also know first hand from their very outdated dark ages father that there are a generation of men who don’t want to accept equality and they already try to fight against it. From talking to them, they don’t want to fight against the people they feel are also vulnerable ie a trans girl. It is more acceptable than ever to come out at school with no repercussions (at least where we live), when I was a teenager many kids were self harming over their sexual orientation being a secret. They don’t seem to question gender confusion as much as the older generations do
Where I do draw the line for me personally is not jumbled clumsy quotes from confused pop stars or confused children. It is people (men) who have a very radical agenda to invade women’s spaces. We can fight them without fighting EVERYONE.
There is no proof or evidence that the majority of trans people or non binary people want anything to do with the radical transgender movement and dislike it as much as everyone else
