There was a similar topic on this recently and I decided not to post my take on it ,but after seeing another similar thread, I guess it would be best to at least say something.
Especially true on communication services such as Aim, Msn, Trillian, anything on the Internet, we all have to realize that one of the fundamental aspects of communcation is missing, and that is the psychological or simply the emotional aspects of the individual.
When we speak with the people we see everyday, family, friends, peers, and strangers, we don't speak to them in monotone and with no emotion (unless maybe you do, if so, I'm sorry for not representing u in this). We have emotions and when we chat, our voice reflects these emotions.
So when we say "Hi", it can be interpreted in a lot of ways. To our family, it reflects our affinity towards them. To our friends, it expresses our gratitude for them. To peers, it expresses our acknowledgement towards them. And finally to the sun, it shows how we're always grateful that as long as there is a tomorrow, there is hope. =D
So therefore in saying so, when a player on wifi uses a kirby and does a down taunt and for some reason the taunt is something derogatory or mean, what am I suppose to get from that? Kirby, his face being cheerful and absolutely happy, who am I to say he is not? On the other hand, my opponent, his character being completely arbitrary to his choice, was his intention just a literal meaning of the words I see?
The fact is I have no right to assume what my opponent means by his choice of words. However, I do have a right to assume that whatever my opponents choices of words are, its there because its deliberate. There is a reason behind it but unless I know this person, I can't go assume the reason.
But in saying all that I said, yeah, in all seriousness, just do what several people on this thread have already suggested. If someone has a mean taunt and you just can't seem to ignore it, do the smart thing and just play someone else. You'll still have fun and in most cases, a lot more fun. =D
