whatever your motivations are, the baggy trend came from skate/snowboard culture, which directly took it from black culture. I dont think its a bad thing, but you have to realise skiers just didn't invent tall t's out of nowhere. So maybe you dont mean to, but you're still ripping off black culture.
Same with the old school hip-hop. It was made by black people for black people, and while i think its great that we are all free to enjoy it, make sure you remember it wasn't made for you. Just like country isn't targeted at black people.
So keep self expressing yourself through trends from the hood, but don't be so ignorant as to say you aren't emulating a culture you will never be part of.
