I honestly pay them no mind, they've become so commonplace. When everyone has pink hair or wears dark clothes with chains and spikes, you've sort of lost your specialness.
The question, ultimately, comes down to whether you can get a job and carry on the lifestyle, while working. I would never hire someone with a thousand spikes or studs in their clothes, as a furniture mover, nor would I hire someone with chains running from their neck to their wrist, [voluntary self incarceration?] to work on any machinery with moving parts.
As for the ones, who wear their pants below their butt, and spend their life with one hand holding the pants up and the other hand listening to the Ipod, they are a waste of human skin and O2. Just taking up much needed space.
