I think you're doing the right thing by avoiding them. This may be an opportunity though. If there are others in your group that don't want to ride that way, maybe you could organize a beginners run. I went on one when I got my first sportbike and it was awesome. Everyone took it slow, never left anyone in the rear and we did a little "class" before we ever left the parking lot on hand signals, rules, etc. You never know, there may be someone else in that group that wants to ride but doesn't want to stunt, etc. I say spread the love and knowledge all you can amigo. The more you can tech a young rider the better. New riders will usually follow what everyone else is doing, so you could be saving someone's life by taking a newb under your wing. Just my .02.
