I know that Emily Lake has someone who is a close relative who is trans and while Emily seems supportive, I know she's not thrilled with the idea of puberty blockers because of potential future harms, especially if the child feels differently down the line, and surgery even more so.
I have two relatives who currently identify as trans. One of them is male, and identifies as a woman. They were pretty gender non-conforming as a child, and they made the decision to undergo transition at the age of 21. They have decided NOT to have any surgical procedures, and is only taking hormones. Part of their decision for that approach is that they did a LOT of research. And while they're pretty confident that they identify as a woman, they are also aware that they have some other mental health conditions that could be contributing to it, and they want to have the option to go back to living as a man if they later change their mind.
Kudos to my now-niece for being extremely rational about the whole thing. She has my full support.
The other is female and has JUST turned 18. They started taking testosterone just before they turned 17, after only have expressed anything remotely resembling a transgender identity for about a month, and after having spent a grand total of 30 minutes talking to a gender specialist. They are bipolar, and have been struggling with depression and anxiety for several years. They're scheduled to get their breasts amputated in May.
I don't think my younger niece is actually transgender at all. I think she's confused, I think she's had a really hard time dealing with her parent's divorce, and I think she very much needs counseling - which she refuses. I fear that she is going to regret the permanent changes she is making to her body. None of us - including her older sibling - believe that she is actually transgender.
I love my younger niece, and I will always be here for her. But I think this is a horrible idea that will end very badly, and I fear the toll this will take on her mental health.
