Change takes time. As I said before, the exclusion of homosexuals is a relic, and I think its days are numbered.
If only this were true. The BSA had no policy or statement on homosexuality until the early nineties and did not ban homosexuals until 2002, IIRC. If anything, this is a fairly recent change to define Scouting by the Mormons and the Methodists. One has the largest number of participants while the other has the largest number of units, combined they essentially run the BSA.
I am heartened to hear that so many folks are finding tolerant troops. I loved scouting as a kid and really feel that the patrol model is a great tool for teaching kids leadership skills that are practical and long lasting. It also is a great base for a very broad knowledge set and practical problems solving that is not often taught in school.
My recent discussions with professional scouters had lead me to believer that there was no tolerance for tolerance. I'm glad to hear that the subversive are staying low and avoiding the scrutiny of the BSA.
As for the exclusion of atheists, it isn't all that bad anyway. The first statement in the section that describes the Boy Scout policy about religion says that the BSA will not do anything that defines what it means to believe in God. In practice, that means pretty much anyone can participate. Many state laws refer to "acts of God", and later say that for the purposes of the law, God=nature.
I expect this will be taken care of. Every professional scouter I have met recently has freely stated that the BSA is fundamentally a Christian organization that has some tolerance for other religions. Phrases such as "Christian Values" are bandied about with no sense of irony.
It seems the BSA is moving further to the right as a reaction to society moving further to the left. As a scouter who earned his Eagle before any of this, it makes me hesitant to even mention my association with the BSA, even though I have a lot of positive memories.
