The problem with doing the opposite of what everyone else is doing is that quite often everyone does something one way because it's a good idea, and sticking to your principles and doing the opposite means you are stuck with something stupid.
Some anticonformists, notably hipsters, insist on fixed-gear bicycles ("fixies") precisely because they're not used by "normal" people.
So they're stuck with a less practical and more dangerous bike that can rip their fingers off even while they're fixing it. Some of them even insist on removing the brakes from their fixies. And then adding a bunch of stuff that's about as effective as a giant spoiler is on a car.
Now, fixie fans insist that if you know what you're doing, a fixie is perfectly safe, but the person that is buying a fixie just to be different is the kind of person who looks down on people who know what they're doing on a bike.
Who admittedly can be a little hard to take seriously.
