Japan is the most racist country

Many Japanese people are extremely racist. They think every non-Japanese person except White people are inferior. Japanese people especially love to insult Koreans and Chinese. On 2ch and 2chan, there are many racists who insult Korea. There is
even a special board called "Nida" on 2ch for people to insult Korea. Japan is the most racist country in the world. I am very ashamed of this sad fact.

私も日本人です。
I am Japanese also.

they try and make themselves to be the cleanest most peaceful culture.
but what original inventions, used world wide, do we use of theirs today?

examples:
europeans: inventors of the scientific method and modern rationalism, along with pretty much all the discoveries they have entailed in modern technology. modern physics.
medeterranians: revolutionized military science, great strides in the fields of geometry and ancient philosophy.
south asians: first cities and organized civilizations. cotton gin, water wheel, first artillery shells. wrote first books on medicine and mathematical methods for calculus.
mesopotamia: first to make the innovations that allowed for the creation of empires, including mailing system. invented algebra as we know it and modern number systems, written language, windmill.
mainland orientals (chinese): printing, hydraulics, gunpowder, paper, holistic medicine, many mechanical devices.
pacific islander: made great strides in improving upon the inventions of others, but cannot claim originality for anything in widespread use today, or anything that lead to the inventions in widespread use today.

japanese and koreans are great but to claim that they are necessarily more civilized than pretty much any other civilization is wrong.
