There really is a huge cultural difference between motorcyclists and bikers. You could call it a family feud, and I say family, because at our cores, we are all people on motorcycles...Both groups share a love of bikes, but that's where the similarities end. I don't want to turn this into a harley-bashing rant, but the truth is that most motorcycle fatalities are of a >40y/o man who is riding an over-weight, poor handling, poor performing cruiser-style bike, and has been riding it for less than five years. A biker rides with an emphasis on status and image, whereas a motorcyclist rides for potential performance and personal improvement with an emphasis on safety. The sportbike crowd has their fair share of idiots (squids) too, but these tend to be young people (and all young people of any demographic are, well, idiots) The cruiser crowd with their constant unnecessary revving, wanna-be bad-a$$ persona, and general lack of good moto sense, give motorcyclist a bad name. But like I said, we're all family, and who doesn't have a dumba$$ uncle in the family? I have two.
It's just a matter of what's important to you...safety/performance or image/status.
