It's not hated on D:-- I find it cool and am personally jelous of anyone who can pull itoff. I think it's just that people aren't that accepting these days. There's nothing wrong with showing off your style or loving certain things. And you know why some people don't like it? Its cause they're too afraid to show off their own style. I think people who are truly genuine are people who follow their desire. You can't always be accepted but know there are people who appreciate you :)
It's associated with a dismal outlook on life that many self-styled emo/goth kids share.
Appearance-wise, I suppose it's just out of fashion. But fashion trends change, and what's out can come in again. Modern pimps brought back feathered caps from 17th-century France, so hey, anything is possible.
