This is an interesting thing to me..

Recently I was talking about how Roger Ebert was saying that Video games are not art. Well something that a person mentioned in a comment was how it seems that Ebert has fallen into the "No True Scotsman" trap. Saying that games can be art but they can't be high art. That theory is pretty interesting to me because it also makes me think of what some people define to be a casual\non gamer and a true gamer\ hardcore gamer. Replace Scotsman and True Scotsman with those.

"This person plays games on PC, Mac, Handhelds and Arcade", "Ah, so this person doesn't own any home consoles? Then this person is not a gamer!" "But they play quite a few games on those systems and get quite a few new ones each year!" "But they don't have the systems I'm endorsing so they aren't true gamers!" or "No true gamer would play games on one or a few systems!"

Some people have taken that even further to have gamer just mean true gamer as well.
