Tell that mutherfucker some knowledge straight from general shredgnar.
Every article of clothing that anyone puts any sort of thought in choosing and wearing incorporates two components; a personal choice based on intrinsic evaluation of it's appearance, and a consideration of both what popular culture dictates looks good, and the choice of people you look up to for coolness.
Denying the value in any single branch of popular culture in denying all of it. You might as well throw out all the Killers and Citizen Cope CDs that higher browed poser journalist listens to and assumes the meaning of.
Skiing clothing is misunderstood by the general population. The choice of clothing does indeed have utility and meaning:
Tall Ts and tall clothing is a mirror off-hill image of what skiers, and fucking snowboarders, wear on the hill. The reason for wearing such clothing is not only because of comfort, but also because of it's metaphorical significance for the sport itself. It's an indirect indication of what we do.
Baggy clothing on the hill has been chosen to mask the more awkward movements of the body during aerial and rail maneuvers, thus having practical and chosen aesthetic value, and generally speaking the more material you have to wear, the warmer you are. The extra length additionally keeps snow from ripping your back and ass apart, which many of us know, is one of the easiest ways of destroying yourself after a simple fall on a kicker.
These styles are also, like any other style, dictated by the individuals who lead the cultural movement. In this regard, surely many kids out there take no consideration in their dress and ignorantly grab whatever attire they see is popular. But skier kids are no different from anyone else. At least their choice has some sort of significance; It's certainly more meaningful than baggy clothing within hip hop, which is derived from the inability to procure a belt in prison.
So no, freestyle skiers are not trying to be black, nor does their choice in clothing have no use. Tell that bitch ass to throw his cheap monday pants and shitty old navy cardigan in a bonfire, because he too, like the rest of us, directly or indirectly fund some sort of shit show that is fashion.
(I'd go into the musical influence upon skiing but I'll save it for another time, finals n shit.)
