Ya korean society has alot of foreigners and koreans bent out of shape. Trust me this is not a heavy issue here in korea. To be frank, suicide, pediphilia, competititive education system, low birth rate, abortion, animal rights, racism, patriartical rule, prostituition, alcoholism, divorce, sexism, workers rights, tuition, international territorial disputes are the heavy issues. Those are the issues that are reported in the korean herald on a weekly or montly basis. Reading the korean herald has become depressing and dispairing like most news sources.
Nature versus nuture can alter the personality of a person. Simply what we regard as beauty is not innate, but cultured based on our social background. That is my argument. Challenge it! In other words duality is circumstantial, not absolute, because we must have minimal mutual attraction which implies a physical attraction which is culturally based. We can easily find ourselves psychologically compatible even when we are nationally or politically opposed. For example, Koreans generally dislike Japanese, with emphasis on generally, because that has to do with a long standing historical conflict between the two nations. Japan occupied Korea from 1905 unitl 1945, however, during that time Japan had committed many atrocities toward Koreans which has been included into the Korean educational system, therefore, a majority of Koreans are educated of their own history which surmounts to a massive conflict with the Japanese. Likewise, the Japanese have a factually conflicting side of the story. The Japanese do not see themselves as evil, rather, they occupied korea and then left.
To this day, Korea and Japan do not get along on many issues. I hardly consider socionics would have any influence in this matter whatsoever, unless subtley and personally.
As a matter of fact, I have spoken with a Korean who has explicity denied his own son the right to marry a Japanese girl because she is Japanese. That has nothing pertaining to socionics unless abstractly. I do not consider socionics a physics of the universe, which "governs every single aspect of reality", even socionics often state that they can not account for all factors. Therefore socionics is limited so do not make such grand statements unless you can support them.
