Sorry, but yes I can - if the only interaction I ever have with them is in a game and they act like a jerk then I'll judge them accordingly. My point is, if one is not a jerk in real life, but one acts like a jerk in a video game, don't be surprised if people judge one to be a jerk when the only interaction they have with one is in said game. Actions speak volumes, just as much within an interactive game as without. This is not a case of judging a book by its cover - people act like jerks in a game and are judged by others on the basis of those actions, regardless of who they are in real life. If the only interaction I have with them is ingame and I have no other interactions on which to base my judgement, no matter how openminded I might be about who they might be outside of the game I'll judge them on what I see them do ingame..
My motto is that if one doesn't want to be judged to be a jerk, don't act like one. Simples.......
