The thing is that I am not sure you are accurate. It would be kind of like saying how the priests and such you knew in the local catholic church is the church you want, not the one aiding and abetting child rape and spreading dangerous lies about condoms. That is the real church as an organisation, you just where involved in a group that did not represent the real organisation.
Except for the matter of timing. If the RC church started doing all of those bad things in the nineties I would be calling for them to return to their pre-90's state of not aiding and abetting child rape, etc. Becuase I would have remembered how good the RC church was before those crimes. (hypothetically assuming that I thought the RC was otherwise good)
In contrast, the BSA was a very decentralized organization until the 90's when it felt pressure of abuse cases. As Rob mentioned they reacted poorly. Women are allowed to be leaders in the BSA, but not openly gay men. So, save the tent sharing arguments. This is pure bigotry from on high. The point being that two deep leadership, when properly employed, eliminates almost all risk of abuse and the BSA has done a very good job of training its leaders on this. Yet, they will not allow a council or troop to be open to gays.
The truth is that few troops would be open to gays, even if the BSA removed this rule. Most sponsoring organizations would be opposed and the leaders of the troops would have the final decision. But, the few that would like to be open to gay parents or well trained gay scouts are not allowed to. They are allowed to have convicted rapists, felons, drunks, or even retired catholic priests, if they want, but not gays. It is irrational and counter to much of what scouting was about prior to the mid 1990's.
This is why when I a atheist friend brought up his son joining scouts I suggested he be open to this. I think you can find groups that are decent despite my experience with scouting in this area and my issues with the BSA.
True, you can find troops that do not toe the BSA line where it interferes with their operations. But, wouldn't it be better if the BSA returned to their non-centralized state of accepting the troops judgment?
The other problem that the BSA likes to ignore is that many former supporters of the BSA are no longer able to support them. Anti-discrimination policies at many schools, religious organizations, and supporting charities make supporting the BSA and local troops impossible. As more organizations review their anti-discrimination policies the BSA will become even more dependent on the right wing conservative churches that are pushing for the discrimination in the first place.
For me it is akin to seeing a family member becoming more and more dependent on a cult as the cult tells them their real family is the spawn of satan and trying to buy their love. It really disturbs me.
