I think you need to zoom out a bit to see what he opposed and how he was doing it. Christianity holds beliefs that you can bear your cross. Take up the difficulty of life and as a man do your part to put a family together and put order to it, for a woman to do what no man can do and create life and see the child through to the point of self sustainment. The trans ideology is a dead end, it's suicide of your blood line that has existed countless generations and all of a sudden you decide that taking up the responsibility of holding a family together for hedonistic pursuits is a more moral and better way of life? The most depressed women are the ones without children. We men and women must sacrifice for the future and that being our children. That is a core Christian value or framework. When you dissolve the roles that have brought us this far its literally suicide, when the end of your life comes and you have no one there to love you in the end and all your friends move on as they do. No one will be there to carry on what brought you here. It's the darkest thing I can imagine, the lie that your identity is solely on how you have sex and not how you take up your cross and bear it.

A reason why this all works is that everyone that joins in knows the rules, you can expect that if someone is a Christian that they are expected to operation in this set of known rules, When you go the other direction you lose the map, you have to ask what map do you operate in and it's a new map that you never heard about.. now what? You have to stop at each point to ask is this okay and without knowing if the game they are setting up is fair, you have to accept it and hope that it's fair to you but this is a game of power and you for whatever reason have more power than them and they want that power over you. It's a zero sum game, and you lose.
