if they merged the groups under the same leadership but kept the distinction between boy scouts and girl scouts I wouldn't mind but they're basically abolishing the "boy" distinction and keeping the girl one
I agree. The "Girl Scouts" should either be opened to males as well (though being a member isn't really as prestigious as the Boy Scouts and IMO I don't think it teaches the same level of values), or the organizations should be combined.
The point is also kind of moot, because they're too separate organizations with a similar name. It's a bit like if a boys-only school started allowing girls, and then you point at a totally unrelated girls-only school and say "well they aren't allowing boys in!" It's just not relevant.
