If you want to ignore the context and stick exclusively to the word "idiot" as an isolated event, the discussion has no point.
That's not fair at all. Anyone here, and I believe all of us, would understand that it is not nice for anyone to call someone else an "idiot"...there is no argument there...we would all agree with you...how all of us would tolerate the comment is purely subjective. What I believe Fks is concerned about (and rightly so) is that by use of a rather common and ultimately benign word in the "gaming world" has been the basis for a ban...even if the ban is temporary and for one week.
It is clear that you felt deeply offended by being called an "idiot" by someone who was acting the role of a sore loser, but now you are arguing against "point of view." Context? Okay, that is an excellent point from which to start...the context is you were in a match with an opponent who could not tolerate how the game was going...win or lose is less relevant in this context than the final events of that match. In context, you wanted to express a very simply message: "Good game." This is fair, this demonstrates good sportsmanship, and is ultimately a friendly gesture. Then, this player decides to use the opportunity to insult you–there is nothing good about this at all. Was it rude? Yes. Was it uncalled for? Yes. Was it unnecessary? Probably so.
Now, in the greater and broader context of things here at this site, so often we have cautioned players that by using the "BattleChat" that they are taking a certain amount of risk by doing so...no one is obligated to use it, or to even respond to it when receiving a message, and there is always a fifty-fifty chance of getting a message back that is unwanted–those are the odds and the reality of things in context of this site. You wanted to send a friendly message, but your opponent was not interested in being friendly. That is really a pity, but unfortunately, such jerks do exist on this site.
Just because you sent a message in good spirit does not insure that it will be received as such, and you cannot expect your opponent to engage with you on the level you want.
In short, if he had called you something truly vulgar, or had launched an offensive against your family and friends, then I would say such a person needs a lesson in the wood-shed. He called you an idiot. Why should it matter to you what your opponent thinks of you??? Their opinion is just ONE opinion and should count for NOTHING!!! Instead, you allowed the insult to affect you, to disturb you, and to upset you enough that you wanted a kind of justice. I understand very well...no one here knows exactly how this match unfolded and how you felt being given a nasty reply...we all have some idea about as we have all received some kind of idiotic reply of this kind. Still, you keep posting in reply to Fks' arguments, and you seem, at least to me, to be incredibly defensive...why is that? You didn't do anything wrong...or did you? Do you feel that you may have done something during gameplay to upset your opponent?
At any rate, the main part of Fks' argument, I believe, is that people should not have to fear being banned because they use terms that are basically innocuous compared with all of the other expletives that are available and are too often used. I agree with Fks...he has a very valid point.
Buck up, never say die, and let these kinds of chats be like water off of a duck's back...please try not to let it offend you too much.
