The Boy Scouts of America (BSA), one of the largest private youth organizations in the United States, has policies which prohibit atheists, agnostics and, until January 2014, prohibited all "known or avowed homosexuals", from membership in its Scouting program. The ban on adults who are "open or avowed homosexuals" from membership was lifted in July 2015. Prior to these policy changes, BSA had denied or revoked membership status or leadership positions for violation of these foundational principles. The BSA had contended that its policies were essential in its mission to instill in young people the values of the Scout Oath and Law.
The organization's legal right to have these policies has been upheld repeatedly by both state and federal courts. In Boy Scouts of America v. Dale, the Supreme Court of the United States has affirmed that as a private organization, the BSA can set its own membership standards. The BSA's policies have been legally challenged but have not been found to constitute illegal discrimination because as a private organization in the United States, the BSA has the right to freedom of association, as determined in the court case. In recent years, the policy disputes have led to litigation over the terms under which the BSA can access governmental resources, including public lands.
These policies have led to various disputes and controversies. In 2012, both Republican presidential candidate Mitt Romney and then President Barack Obama stated that they opposed the ban on gay Scouts. On May 23, 2013, the BSA's National Council approved a resolution to remove the restriction denying membership to youth on the basis of sexual orientation alone effective January 1, 2014. The policy for adult leaders remained in place until July 27, 2015.
According to its mission statement, the Boy Scouts of America seeks "to prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Law". All members are required, as a condition of membership, to promise to uphold and obey both of these pledges. The texts of the BSA's Scout Oath and Scout Law for Boy Scouting have remained unchanged since they were approved in 1911, and every member agrees to follow them on his application form.
