Caster, your behavior is EXACTLY the sort of behavior I just spoke of.
I see, so any comment, analysis, or criticism is instantly invalid because someone isn't directly from that culture. Even though you never defined that culture as social differences, historical belief, minority groups in Japan, familial belief differences, or the year your child grew up and what shows he watched as a kid defining him. Not only the argument hold a DANGEROUS amount of arrogance and apathy, it was never even defined or explained. It simply went back to "You can't understand (because the metaphorical "you" said so), therefore I will not make an effort because I have already solidified my stereotype of you as ignorant and impossible to communicate with. Furthermore it is impossible for me to understand you, so I will make no effort."
Then this is followed with, "i think it is waste of time any further."
Thus, communication ends abruptly. There is no attempt to understand, there is no attempt to communicate.
On the personal level this is how relationships that could be wonderfully fruitful are tossed aside like garbage. When there is an argument, there is nothing but anger and hate rather than debate and an effort to express one's thoughts and feeling and understand the other. On the political arena, it leads to assumptions, fear, and out right lies about the intentions of the other. On the international scale it is the last step before inevitable war.
Again, this sort of (lack of) thinking is one of the most dangerous aspects international interaction. When one side takes on this sort of immature, judgmental behavior, you end up with horrible results.
I can only thank you for one thing, showing me a perfect example of this behavior on a small scale caster51. I do hope you serious reconsider your behavior for your own sake and all those who have lost the opportunity to share and learn both from you and what they have to offer in regards to experience being given to you as well.
