If you don’t want your son to attend a church sponsored youth organization there are alternates.
The Baden-Powell Scouts’ Association (B-PSA) is a youth organisation in the United Kingdom, with affiliations in various countries. Baden-Powell Scouting focuses on the importance of tradition in the Scout Movement. Japan, Argentina, Malaysia, Malta, Germany, Denmark, Ghana, Canada[1] and the United States have traditional organisations that are affiliated to the Baden-Powell Scouts’ Association (B-PSA).
The Baden-Powell Scouts’ Association shares the heritage of the youth Scouting Movement, however they believe in a traditional way of Scouting which closely follows the program set out by Lt. General Robert Baden-Powell in his book: Scouting for Boys.
The Baden-Powell Scouts’ Association was formed in the United Kingdom in 1970 by the Reverend William Dowling when it was felt that The Scout Association was abandoning the traditions and intentions set out by Baden-Powell in 1908. The Baden-Powell Scouts retain the belief that the essence of the movement should be based on outdoor activities related to the skills of explorers, backwoodsmen and frontiersmen.
