The Boy Scouts of America have lagged a little in trying to keep up with the advance of progressive values. The organization’s national council voted in May 2013 to lift its ban on gay scouts, and in 2015 the organization voted unanimously to allow gay scout leaders, citing both “the rapid changes in society” and “increasing legal challenges at the federal, state, and local levels.”

On Monday, the Boy Scouts announced a step that the Girl Scouts of America had already taken, opening enrollment to transgender applicants.

It’s a big step, but transgender boys submitting their applications had better throttle their expectations of boyish fun, as other progressive steps taken by the Scouts have led to the banning of water gun fights and fights with water balloons that are non-biodegradable and larger than “ping-pong ball size.”
