Every clique is elitist and has to trash talk their rivals even if they really aren't rivals. Gamers have always been this way, even before computer games really took off.
One time I was at a games convention in Minneapolis and was sitting at a table playing an RPG. A guy walked up and watched us for a while and then launched into a rant about how we were all stupid for playing dumbed down games like RPGs instead of TRUE games like war games that actually took thought and intelligence. We were going to be the downfall of REAL gaming! He went on and on for a while then walked off still berating us under his breath. We sat around for a moment, shrugged our shoulders, and went on playing.
Oddly, many years later I was at GenCon and playing a game of MtG with a buddy (between RPG events BTW) and a guy walked up and watched us for a while. He then broke into a rant about how we were all stupid for playing a dumbed down game like MtG instead of TRUE games like D&D that actually took thinking and intelligence. We were going to be the downfall of REAL gaming! He went on and on for a while then walked off waving his arms and muttering. We shrugged our shoulders and went on playing our game.
PG cRPG gamers have been getting bad about this (though I've only been e-ranted) and you see it between rival consoles, too.
