My two cents: claiming Japanese "always make a better arrangement more than the original version [sic]" and then dismissing Westerners as "narrow minded" because they may not accept his/her silly opinion as "fact" themselves sound like the positions of a rather narrow minded person. I'm also willing to bet said person doesn't really have a great appreciation for classical Western music to begin with, which explains his/her flippant attitude towards the great masters like Bach.
