Isn't BSA, and Venturing too, basically a religious organization? The oaths mention God prominently, and they exclude athiests and agnostics. (I'll give them credit- they do admit Hindus, Muslims, Wiccans, etc.) And there is the issue about excluding homosexuals from leadership roles including as adult volunteers because it "conflicts with the oath" which, I have mentioned, is religious.
The National Council has commanded local chapters to revoke nondiscrimination policies where they have instituted them, and chapters have had their charters revoked for refusing to do so.
BSA v Dale has upheld the right of BSA to be exclusatory. This does limit their ability to access government funding and other resources, now, though. They're had to abandon sponsors like military bases and public schools. And their right to use public lands has been challenged.
I want to point out that I find most of that last paragraph a bit extreme. Heck, prayer groups can use public spaces. There are religious organizations using office space on every US military post. Why not BSA?
I would love to find an outdoors group for my daughter when she is older, but I doubt that scouts is what I'm looking for. I recognize it as a basically positive organization, and thus I'll support it, but not by admitting my daughter. :(
I know that Girl Scouts is a different animal entirely (they accept gays and allow an alternate oath that omits the word God) but, as aaron mentioned, I really don't see a need for my kid to spend more time selling cookies than hiking...
So, I guess all I'm saying is that I'm rather interested in alternative for girls, too. :o)
