I thought it a bit strange that the National Jamboree had such a jingoistic vibe, My troop (late eighties) kept it pretty low key. Its sponsor was a liberal protestant church,
I suppose it depends on how forcefully the national organization imposes its will on the individual councils, and how forcefully they in turn impose their wills on the troops. It probably got a lot worse after the BSA started chanting “Hey Hey, we’re anti gay” at the Supreme Court.
If a troop (in my day) wanted to be right wing christian, there were probably a lot of tools in the Scouting ideology. If it just wanted to focus on camping, it could do that too. But right now-- yeah, I’d think that joining a troop means joining a exclusionary organization that does not reflect my values.
