I hurt my thumb a few weeks ago, and skied without poles since then.  last saterday I initially used poles, but dropped them from the lift on my first run (first time in 19 years).  When I picked them up, my thumb was hurting still (not totally healed), so I let my snowboarder friend, who was skiing for the day, use them.  I've gotten pretty use to not using poles, and have fun.  its still skiing.
There isnt a ski police.  You are allowed to ski how you want, don't let other people tell you what to do.  Style is what you make it, so do what you want goddammit, and stop arguing about something pointless.
