Thanks for the reality check. I completely concur about changing this behavior being well-nigh impossible. Given the personalities involved and other nuances of the situation, it would require more social finesse than I might be able to muster to affect substantial changes without permanently alienating one or both leaders. It is also for this reason that I am reluctant to contact any other authorities.
I am in a bind, though, because even though my son has discussed his negative feelings about these attitudes and events, he is eight: I would hate to pull him out of a peer group, since it is tough to be the "odd boy out," even if you know it is best. I think the best thing may be to come up with an exit startegy (e.g., "too many other activities, is it okay to drop scouts for now?"). There is a pack in our town, and I am sure it is much more relaxed; the whole point of doing the other group, though, was that it was made up of classmates (they wear their uniforms to school, for instance).
More opinions are most welcome.
