I think it depends on how they handle the girls and boys. Scouting is co-ed in a number of countries and they may have quite a bit of experience in handling the issues.
Intersectional queer theory with androgenuous underlying motivations and dispensation require that boys and girls never be only with their own gender. That causes the formation of stereotypic gender based normative behavior that skews the data right and left making it impossible to achieve heterogeneity in a timewise manner to meet the exploding LGBTQ+A regulatory interests in such matters.
I don’t know. The BSA has pushed teen boys to do things that girls would never be pushed to do. Having girls will change it like having girls on a football team or boys on a girl’s team.
Already there is a backlash in sports where males who ‘identify’ as female are allowed to participate in girl sports and end up walking away with all the trophies. It’s a farce. And one league banned it.
