Homosexuality is one thing, and can exist as an inclination fought against. Trans is completely difference, and even if it is simply mental illness, is based on a rejection of God the creator and of His creation and in fact of created nature.
There is no way of legitimizing any of this or making it acceptable for a Christian. Even if it were regarded as a form of possession or mental illness, a person with those attitudes does not have the fundamental faith to be baptized.
This is also disaster because it takes away the protection of Catholic doctors, parents and teachers who reject “transsexuality.” There is no such thing possible in Christianity but now the Church has thrown them - as well as the deluded victim him or herself - to the wolves,
I remember when people used to try to help these people feel comfortable in their own bodies through mental help. Now govt and half of society encourge the mental illness and make it illegal to provide effective therapy help, and hide it from the parents if they are minors.
