As an Eagle Scout and a former Scoutmaster, I believe I can comment on Scouting. And yes, I'm an atheist. And yes, the first time I was ever offered drugs was from another Boy Scout. Didn't accept.
I used to go to "The Church of the Sunday Funnies" (ie, Sunday newspaper reader) but not even now.
As a former Catholic, I also can put a dog in the hunt. But this thread is about the BSA, not the Catholic Church.
Like most institutions, the MAJORITY of leaders are fine people. They are parents and former scouts that find value in the BSA Values. And I'd say that there was a lot gained by those who participate.
Do I think there needs to be some changes? Heck yes. Exclusion because of creed or sexual orientation is archaic. Exclusion because of behavior however, is not.
So if you can teach scouts how to tie a knot, just don't tell them you do it in some BDSM dungeon every Thursday. And definitely don't take them on a tour.
Recognize that kids really just need to be kids. That being able to distinguish among the various kinds of Apis Mellifera while working on their beekeeping merit badge is important to them.
When they are 18 and adults, children are no longer a protected class. And hopefully are on the road to making decisions for themselves.
But to take advantage of a child as based on our current laws, is definitely a heinous act and not to be tolerated.
The BSA should NOT have covered up anything. Change can only occur when there is motivation to change. And hiding these abuses is truly heinous. The choice should be the child over the organization.
Nothing prohibits a person or group of people from founding other similar organizations. Happens often enough.
