One of these girls ("Grace") has Asperger's, her parents are separated, she showed no prior signs of transgender identity, and then suddenly started demanding she transition during COVID lockdowns when normal social interactions got thrown in the wood chipper. Those are all danger signs that maybe caution really is advised. And when her mom wanted to slow down the rush to medicalization, which was entirely reasonable, her dad didn't. So now she's alienated from the mom but NOT the dad.
You know what that sounds like to me? That sounds like one parent is pitting the child against the other. Which is sadly common among separated couples even without issues of transgenderism.
Did you notice that domestic conflict aspect to the story? I bet you didn't. Because it doesn't fit the narrative you want.
