Each year, the Boy Scouts of America (BSA) have a national gathering, the Jamboree. This year it is scheduled to have three concerts over the ten day affair, but two of the three artists involved have declined to participate, citing the BSA's current ban on lesbian, gay, bisexual, and trans (LGBT) folks from being involved. Train withdrew their support on March 1, stating that they would reconsider this of the BSA makes the appropriate changes. Carly Rae Jepsen withdrew her support on March 5, stating she is a supporter of LGBT rights and cannot condone the choice of the BSA to maintain the ban.
This ban includes "open or avowed" homosexual people, as well as atheists and agnostics. This has been challenged in court, to the Supreme Court even, but it has been upheld, not because of an ethical belief, but because as a private organization, the BSA can set their own membership standards. It may feel like an unfair policy to many, and an outdated one, but under the current constitutional rights, it is indeed legal.
