What you have written is how it is seen in the West in early 21st century. In the mid and late 20th century it was not seen like that. And even now a significant part of the world doesn't.Suggesting that there might be a “cure” for being transgender is highly problematic. Being transgender is not a disease or a condition that needs to be cured. It is a valid and legitimate aspect of a person's identity. Promoting the idea that being transgender is something that needs to be fixed or cured can contribute to harmful attitudes and discrimination against transgender individuals. It is important to respect and affirm the identities of trans people and support their rights to live authentically and with dignity.
I don't want to express my personal opinion on this topic, I just want to say that it's quite possible that some kind of backslash against trans rights (or even LGBT rights at all) would happen at some time between 21st and 24th centuries (in fact, in some countries it's happening right now).
