Just for full background, the American College of Pediatrics (not to be confused with the American Academy of Pediatrics which is the actual professional body for paediatricians in the US) is a right wing organisation who oppose abortion, gay adoption and advocate for "abstinence only sex education" (aka sky-rocketing rates of teen pregnancy).
Doesn't mean that their individual members can't be good medics or scientists, or be right about trans issues, but people on the thread may wish to be aware of the provenance.
