Is it becoming hip to hate hipsters? I don't see what the big deal is. Most of them are kids and young adults who have built up a fashionable culture around bikes. I really don't see how this negatively affects the traditional bike culture. In my opinion it just enriches it. Sure this culture may go out of fashion but when the dust settles there will be a couple of former members who have developed a life long commitment to bicycling.
So please give me a clear reason why these kids negatively affect the bicycle community. Make your argument as to why they are “stupid”.
