As you can see, it's not so much about any particular transgender people. It's about the idea of transgender people existing. Before that, it was the notion of gay people existing. They think it is sick and disgusting and somehow against the will of God. They believe that if we somehow become normalized in society, they will be at a loss to find some other type of person to demonize and use as a political scapegoat.
