Today, I read a piece by Paul Spinrad which describes my thoughts much more succinctly than I could hope to:
In politics, I think there are two competing motivations for voters to support a cause publicly. One is to influence the majority to agree, to make changes that you believe in, and the other is to distinguish your opinions as superior to most other peoples'. These two motivations generally cause people to act in similar ways, but I've found some "tells" that reveal the underlying elitist motivation.Paul goes on to use this example to criticize anti-religious atheists for their counterproductive, divisive tactics. I think this principle applies much more widely, especially anywhere elitism and the "cool factor" can be found. In order for a movement to be worth joining, it must be worth it for that movement to succeed; anything else is fashion and a waste of time.
Under a democracy, the elitist motivation is self-defeating: If your true aim is to distinguish yourself from the masses, you really don't want your side to win-- your aim is better served when more people vote the other way, and then you can be disgusted with most peoples' stupidity and wash your hands of responsibility.
Bringing this back to bicycling and bicycle commuting: Some people fear their pastime might become popular or trendy, and believe this will somehow lower its value. I don't commute by bicycle because I'm cool, or better than other people. I do it because I enjoy it. I want more people to enjoy it.
