I think ultimately that it's a clash of ideas. The west and the east are ultimately different when it comes to this issue, and approaching this issue from a western mentality when trying to discern the eastern one is a fool's errand. For us in the west, we are much more diverse, both ethnically and culturally. This has led to a mesh of different social norms forming, where emphasis is put on giving everyone an equal chance to live their lives and to respect others equally, regardless of race, gender or sexual preference.
Since East-Asian nations are much more ethnically homogenous, these sort of mentalities are not at all prevalent as they are here. To illustrate, a Japanese person could technically integrate and become an American if he or she wanted to, but an American could never ever really become Japanese. There are people who have lived in Japan for generations, but are still seen as outsiders because of their ethnicity. Since the Japanese mentality in regards to these type of ideas are fundamentally different, there's no way to approach it from a western mentality, as the two are inherently different and thus incompatible. Because the relationships between East-Asian countries have historically been strained, many Japanese people would actually be more offended if an Asian person of Korean or Chinese heritage got Japanese parts, than say a white or a black person for that matter. That's why you rarely see Japanese people have an issue with the whitewashing that is taking place in Hollywood. The majority of them see no problem with it, as they view it as an American adaption of the source material. Of course, their view of "American" is different than ours as well.
The differences between western and eastern mentality are interesting, to say the least.
