It appears that the Mormans are the single largest chartered group of scouts. I'd say reactionary politics are going to be in the mix.

[tangent]Maybe unfairly, I always saw the various scout organizations as part of American, British, German, and Italian proto-fascism. They promote "civic virtues" which seem easily turned into service to the state. I guess it is a question of balance. In our present political environment, we see a lot of Red-baiting rhetoric from right and a middle-left government that seems content to increase enforced private access to the public and individual purse. The old fascist vs communist construct looks dated as both parties embrace aspects of both systems.[/whoopsie]
