The organization began allowing gay youth in 2013 and ended a blanket ban on gay adult leaders in 2015. In 2017, it made the historic announcement that girls would be accepted as Cub Scouts as of 2018 and into the flagship Boy Scout program — renamed Scouts BSA — in 2019.
it is, BUT, if you read between the lines of the requirements, there’s plenty of room for pragmatic atheists (in pragmatic packs/troops). It’s not perfect, but overall Scouting has absolutely embraced inclusiveness.
A big part of Scouting, at the organizational level, is fund raising. Without funds, you can’t afford the uniforms or the events or any of the things that make Boy Scouts a social group.
Historically, the Mormon Church has been a major contributor and facilitator of Boy Scout troops, particularly through the American Midwest and Southwest. Catholics and Methodists are other large scale feeders for the organization. Yes, you can read between the lines. But show up with your “pragmatic atheist” merit badge, and you’re not going to be particularly well received by other troops who came up through religious organizations.
Jews and Muslims haven’t have it particularly easy integrating with the Boy Scouts, either.
