It's really worth remembering, the anti trans hate they are spewing has nothing, at all, to do with trans people.
It's a small, not culturally supported segmented part of the population that they are sure they can make 'other'. If they could do it to red haired people more easily, they would. All of the messages, rhetoric, framing, etc, is just to attack a small group.
The point isn't some ideal, or moralistic purity, or religious call.
They just wanted a target they could hurt.
