Some real men Republicans are already doing so. Gov Ron:
"...gender-affirming care is a euphemism for disfiguring kids..."
And what does this "real man" think about mutilating adults? If someone believes they are crippled, should doctors in Florida be allowed to cut their legs off? Or if they believe they are blind, put their eyes out?
This trans problem is not principally about children, and if you make it so, you affirm the proposition that the phenomenon in adults is real and that mutilation is acceptable, ethical even.
And once you affirm THAT, you will allow children to be mutilated, because "who says "A" says "B".
