as a pc, xbox 360, and ps3 slim user i find it funny youd care. its a forum, if your so sensitive you can leave it. and yes, playing on console doesnt inherently in itself effect the intelligence/attitude of the player, however you have to take into account the entire thing.
a console isnt just a console, used over the years it grooms the player to a certain expectation. this is teh same thing that causes people to prefer certain model guns or cars over others.
now certain people will "click" with such grooming more then others. as such xbox 360 (microsoft) bred a very aggressive and rude player group. with constant expectations of multiplayer, competition (big one here), isntant gratification, and achievement bragging.
competition, bragging, no or next to no repercusions for poor sportsmenship and attitude, sometimes encouraged....combined with the anomynity of online play...is it any surprise xbox 360 users get this rap?
thats not to say these players dont exist on other gaming formats, or that they only own a xbox 360. its a stereotype...and the one thing about many stereotypes....is that they are true to an extent
now you can either disregard what i said as pointless drivel, or you can take a look around and realize its true.
Are you serious? Do you play online games on the PC? It's the exact same thing.
Try Heroes of Newarth, League of Legends, World of Warcraft, Left4Dead, Killing Floor, Starcraft 2, Battlefield series and the list goes on. You just described exactly what goes on in these games on a constant basis. People are people, stop trying to classify based on gaming platform since you will find they are the same everywhere.
