I only hate a very small subset of snowboarders.
The 11 to 16 year old advanced beginner to lower-intermediate that feels he/she MUST "conquer" that black diamond or double black diamond by side-slipping the entire trail and x-acto knife scrapping it to death and/or killing prior mogul development.
There is a subset of skiers (of all ages I might add) that does the exact same thing. I'd argue that anyone who has ever slid on snow has done it at some point during their skill development.
It always amazes me how strong the feelings against snowboarders are. I find hard to 'hate' anybody who's out having fun on the hill. 'Annoyed' is about the most I can summon up.
