Why do I hate Japan?
There are fascists and racists everywhere, not only in Japan. I even do not hate fascists or racists if they do not pose a danger to me. In a democratic country everyone has the right to say what they want to say, don't they? However speakers have to take the consequences of their speeches into consideration. You may or may not have the right to deny Rape of Nanking, or Holocaust, but for me it is a shame to deny something really happened.
In my opinion Japan has apologized to its neighbors, although whether the apologies were sincere remains a question. However, it is neither possible nor rational to control the minds of Japanese people. The Chinese and Koreans have the right to refuse such apologies. But Japanese also have the right to be not sincere. Nobody is wrong being hostile to each other. However, everyone can earn more money and feel more comfortable being friendly to each other.
Some Japanese think they are superior to Chinese and Koreans. Well, it's their freedom to think so. (In 2ch their are some such things) Do you know the so-called white nationalists? They are the same. They do not break any law by spreading racist messages online anonymously, but they can do better by being polite to everyone. For me, I just close my firefox and close my PC when seeing this. I am not hurt. Being here in NTU, I do not have to go to Japan to study in so-called "Japanese MIT" Tokyo Tech. to earn a good engineering degree. Why do I care about what the rich, prosperous and intelligent Japanese revisionists think?
There are also many Chinese and Korean netizens who hate Japanese to death in every character they type, despite their very poor knowledge about the Japanese society. Well, that's their lifestyle. I'm a Chinese, and I know there are quite a lot Chinese netizens who spend their precious time to express their hate of Japan again and again. They have the right to do so, by the way. But it is just non-sense to me. It's also non-sense of few Japanese netizens to dream about Japanese conquering the world before 2015. Hey guys, are you crazy?
But for China, the case is a little bit different. Living standard of Chinese, measured by Human Development Index (HDI) ranks only 81st in the world nations. China has little democracy, and the environment in some cities is really bad. They are simply not afford of being so proud, even they are the grand grand sons of dragons. (But I'm not saying they're wrong!)
This conflict is very interesting. Economically nobody should behave like this. The show must not go on, guys, although you're proud Chinese, proud Koreans and proud Japanese. The three cultures have been close friends to each other since the very begining of their histories until only about 170 years ago, it is likely that this dispute is only a stupid breeze in history. Anyhow, we are all East Asians and are so much culturally linked.
