Trans was considered a mental illness until a few years ago. They only changed it because of the stigma of mental illness. They didn’t change it because of any scientific evidence. Again, they have no idea what causes it. It very well could be a mental illness. Which is ok btw cause lots of people have issues. Many people de transition so I’d argue that it is something in their brain.
again, you are claiming moral superiority but you still have no idea what causes it. Everyone is guessing. You are no more right than I am.
