I think it was more that he was a little frustrated that he could not explain anything without lingo/terms that skiers/snowboarders use, making it almost impossible to get his point across, and that Conan was being a bit of a douche (surprise i know).
Your completely overreacting. Skiers also do things like that. I'm a skier and snowboarder and have no problem with either because theirs no reason to. Don't pin those stupid untrue things on snowboarders. Plus if you don't like anything that doesn't have to do with skiing being in non-ski gabber then just dont open it. easy as that
