I've found by experience that the fixed gear crowd is a mix like any other. You get people who are the "too cool for you" fixed riders, but you'll also find some decent people ride a fixed because that's how they like to roll. To me this goes without saying, but it's something just to keep in mind. You get jerks in any crowd.

That said, I don't care to ride a fixed gear simply because I learned to ride and have always ridden vintage bikes that were either single speed coaster brake items or 3 speed SA items. I do have a 10 speed that I rode for awhile, but it's in pieces and stored away since I just don't enjoy riding true lightweights.

But you know, we have a system of private property. Yeah I cringe when I see a nice old bike turned into a butched fixed gear item, but hey it's someone else's property. If I'm going to worry about a bicycle, I'll spend my worries on my own.
