Actually the sport was a rowing/crew. Lots of high school teams were there, it involved racing, time-trials, etc. The parent in question has a preference for the usual team sports, basketball, football, etc. I wanted to expose the den to a sport that was relevant to the region I live in, is actually a challenging TEAM sport and requires planning and real effort to be successful. Not unlike the other "traditional" sports.
I got some really good feedback from the other parents, the kids had fun, and everyone learned something new. The cubmaster and all the leadership has been supportive. But yeah, I'm thinking there may be a disconnect with this particular person.
