Oh please. Fixies are no more dangerous than freewheels. Your post sounds like you're assuming the dudes going to go brakeless from the get go. It is no more dangerous then operating a machine for which you have little experience in.

You seem to be putting fixie riders on some sort of holier, more elite than thou pedestal which is pretty wrong. Just as there are bad freewheel riders, there are also bad fixie riders. No one group is intrinsically better than the other because of the type of bicycle they are riding.
