He is walking a fine line in trying to say that the church needs to minister to all people while at the same time trying to discourage the “colonization” of transgender teaching in schools. He is apparently trying to admonish the normalizing of the idea that one can "choose" a gender identity that runs counter to their birth sex.
Where the Pope gets it wrong of course is that people don’t choose their gender identity. It is chosen for them.
We transgender people have fought hard to stay within the confines of what was expected of us and made every effort to conform. The watershed moments came at differing stages of our lives depending on each set of circumstances where we could no longer continue living a lie. Therefore just like gay and lesbians who may have married to try and be “normal”, we did our best to fit in.
The church policy is “hate the sin but love the sinner” but there isn’t enough knowledge or intelligence on this issue within the walls of the Vatican to be able to speak authoritatively and therein rests the dilemma. I actually don’t think that there is deliberate malice but instead lack of solid information.
Transgender people don’t have an agenda to spread a different gospel but want not to be treated like Pariahs. In that sense there is no agenda other than to be allowed to be ministered to and accepted on their terms instead of being shoehorned into roles that don’t fit them.
Religions of the world seem stuck between whether being transgender is a choice or not and even then don’t seem to want people to act on it. But that’s easy for people who weren’t born that way to say. The church would presume to tell the gay man that its fine to be that way as long as you don’t "act on it"; this is clearly not acceptable policy as there are many loving and stable pairings of same sex couples.
Once again we are dealing with the ways of the world versus the will of God and I am betting on the latter having more predominance and wisdom than the former.
