When I was in Scouts we had a leader who liked to fondle boys. We all just passed the word around that you didn't want to go into a tent with him ( he liked to give "backrubs"). No big deal.
But frankly I'm surprised there is such a thing as a male girl scout leader.
Only in Minnesota and parts of Wisconsin.
My daughters wouldn't have been allowed to be in that troop when they were young if there had been a male troop leader. I didn't make it overt to them, but my daughters were not left alone with any male when they were growing up, even relatives.
