Break her nose, and then ask her "who looks stupid now?"
On a serious note, I have noticed the same thing. However, it is coming from people who have actually purchased, or tried to purchase a system. They always say how they really enjoy the gamelpay, but feel stupid when someone watches them play: a catch 22, I suppose. I am sure that, with time, people will get over it. It really doesn't look that much worse than a bunch of guys sitting around alone on a Saturday night, with headsets on, playing the latest flavour-of-the-month FPS, while shouting out as if they were actually in combat.
