Science is a strawman? Interesting. Aren't you setting up another strawman?
Do you understand that "gender affirming care" entails the surgical removal of a person's reproductive organs and the administration for life of artificial hormones to override the body's natural production of hormones?
For example, a man would be castrated, and in the place of naturally occurring organs, surgeons would remove a section of his large intestine, reattach his large intestine and then fashion a facsimile of female organs in the former location of his man parts.
Having been a farmer I can tell you that of all the bull calves and male pigs I castrated, none became female. They all however had no reproductive desires, increased appetites and became delicious meals for thousands of my fellow human beings.
