Wasn't gonna post in this thread, because we've had enough of these threads over the years...
But seeing some of these posts is really irritating. Everyone has their own reason for skiing. If they are on NS, clearly they like it enough to spend time off the hill still talking about skiing with skiers. If you see a bunch of stoked kids wearing tall tees and acting "thug", who are you to say that they shouldn't be stoked? Who are you to propose proper dress etiquette so our sport can "advance"? I love skiing. It doesn't matter to me whether or not it's recognized by the rest of the world, I'll do it anyways.
Another idea. You say we're all the same? When I graduated high school I was the only NSer and one of maybe 5 people who rode twintips. At my university I'm one of about 5 NSers and probably quite a low percentage of freeskiers. The majority of people still look startled by the tall/bright clothing I wear. In regards to the rest of the world, I and every other NSer is pretty unique (as blondie said). Since this is a newschool skiing website first and foremost, it makes sense that people who appreciate similar aspects of skiing would get together here. And evidently we share more than just our love for skiing in common. The fact that there are so many "newschooler" stereotypes proves this. White teenager from a privileged family, listens to rap and electronic music, appreciates style and fluidity of riding, and like OP mentions, wears tall clothing. I personally do fall into a couple of these stereotypes, but rather than be ashamed of it I'm stoked that another NSer can see me on the hill and know that they can ski up to me, ask me the location of a backcountry gap jump, and take a lap on the mountain together.
So lay off the pretentious guidance tips on where you think skiing should go. Enjoy the lifestyle, and let everyone else enjoy it however they want.
