I've talked before about shared identities and the impact on those closest to someone who has transitioned and the impact.
We have the trans widows who talk about the impact on wives and children.
I've mentioned about how the Beaumont society many years ago talked about women having breakdowns over this.
Are we really surprised that very young children might end collateral damage to this?
And yet again we have this idea that the only protected characteristic in this scenario is gender and that's the only thing that matters. It's crap. Safeguarding still applies as does sex.
I see that people say it doesn't matter if they are a girl or a boy, they should just play if they like the child. That's fine to a point - but what we have here is a situation where the kids feel lied to and have had their ability to make informed choices removed. It therefore is a consent issue too.
Nor does it take into account what happens later when any of the four children do find out the truth. How does it impact them? Do they get confused over the relationship? How do the parents safeguard out of school in this situation? There's an issue with parental trust there.
The idea that it's no one else's business what is in a child pants is nonsense because eventually I these children will be teens and it very much will matter and will be relevant.
At some point someone will study the psychological impact of transition on families and close friends and it won't make for light, happy reading.
