In all groups, as well as riders- HD, British, Sportbike, Royal Enfield, etc, etc, there are some very cool people, assholes, and everything in between. You cannot judge or characterize a rider based upon the ride.
Those of us who are so bothered by a type of rider should ask themselves why?
In today's world, I find a rider who happens to be an asshole the last individual that is bothersome
