The worst parts of this are:
* locking in the children with gender dysphoria prevents the self-resolution that 80-90% experience naturally; indulging someone’s mental illness doesn’t cure it
* it violates the privacy of the boys, just as transgender men violate the privacy of women
* it destroys the whole concept of gender based scouting groups when gender is a construct
"Sex". Not "gender". Living things don't have gender. Gender's an attribute of nouns and pronouns.
Just what is it with this squeamish terror of using the word "sex" to describe sex?
