Two things. If you are on the unsanitised part of the internet, I recommend dismissing posts like this one out of hand, unless you want to seethe all the time. You can find groups of people expressing similarly worded feelings towards pretty much every ethnicity. Second, I recommend against overemphasising past grievances and basing future policy on them. That type of thing is meaningless, costly, destructive and escalates very, very quickly. Since you are browsing the Anglosphere internet, assuming that you are Chinese, you are probably far more similar to urban Japanese people than you are to rural Chinese people. There is no point in bellicosity when the circumstances do not even call for such a thing. Both the Chinese and Japanese civilisations have made enormous contributions in uncountable fields. Both share a great, illustrious and common heritage.
