probably for the same reason you have tattoos, identity, the need to belong, a desire to be part of a movement or "clan". human behaviour basically. it's a uniform, a statement, a desire to conform/ not conform, to identify themselves as the same or different.
it's nothing to do with looking like their heroes really, not in most cases any way!
however to belittle someone for doing it is very traffic warden esque!
