The OP came in here looking for a fight as far as I could tell. I don't mind a person putting a fixed gear rear wheel on a bike, done it myself. Most of the people that post in here are interested in bike history and preservation.
Fixie conversion of an actual classic/vintage bike is not going to be looked kindly on in here depending on the amount of hacking and painting that that entails. It seems like the worst excesses of fixie conversions are past, people don't spraybomb their '58 Cinellis quite as often.
