Boxing, karate, and related martial arts—except judo, aikido, and Tai Chi—are not authorized activities.


I don't know the first thing about boy scouts but think of it this way, it doesn't say he can't . I hardly think boxing and karate are related to kendo at all and in aikido we do bokken kata and occasionally try and hit each other with shinai so I wouldn't see any problems. It looks like they're discouraging martial arts that are typically thought of as encouraging an agressive or violent mindset, at least they haven't called Kendo out specifically.
