Tom,
you are very right. Anybody who rides should be my brother. However, I live in York, PA and there is a harley plant here where all the softails, sportsters, and tourers are built. I ride a Ninja, and the amount of crap I get from people here because its not a harley is shocking. A harley riding superior at work said to me, " Rather my sister in a whorehouse than my brother on a Ninja."
My problem with Harley is the company's explotation of the unreasonable obsession that so many people have with the brand. Harley sells more streetbikes in the US than any one else, they spend little money on motorsport, on R&D, their engineering and construction quality is indifferent at best, and yet they keep charging exhorbitant prices because their customers are happy paying big $ for a thoroughly mediocre product to be part of a cult, for something that is ephemeral.
I am an engineer,a consumer, a rider, and an observer. I disapprove of Harley Davidson because they undermine everything that I, as an engineer, hold sacred. As a consumer, I disapprove of their charging exhorbitant prices that cannot be justified considering the R&D, quality, and manufacturing scale. As a rider, I resent the aggression that most harley fans (owners and not) direct toward me. As an observer, I am disappointed in people's obsession with something that is undeserving of it.
All that said, i would still love to ride with any Harley owner if he/she left the attitude behind.
