The national BSA should stick to how to build campfires, etc., and not tell the individual troops who can be scouts and leaders of the scouts.
Uh, the national organization IS the BSA. How do you manage a do-it-yourself conglomeration of disparate scouting units without a cohesive mission, standard, and policy?
What you recommend would BOLSTER the inclusion of girls thinking they're boys in scouting (if a troop wanted it.) The national organization is simply wrong on this issue.
