Spiritual transgenderism is a thing. That’s not an endorsement of the material kind. Far from it. Both are delusions and very dangerous to both the person who suffers under the delusion as well as those around them.
Obviously we have a duty to correct and stand against any cleric of the Church who promotes this nonsense, regardless of their rank. The problem is that people don’t think they can oppose erroneous teaching. We have a duty to stand against error for the salvation of the souls of everyone who hears error, as well as for our own salvation.
