My statement is more part of a bigger issue I have that people tend to argue that the colour of someones skin enables him to speak for an entire culture or even continent, no matter where and how he was raised.
I.E. because someone is black his opinion on a book about Africa is somehow more valuable even though he might be a 3rd generation American who never set foot on African soil.
Or in this case that just because someone looks Asian his opinion on how Oriental Adventure portraits Asian cultures is more valid than the one of a white person with the same upbringing.
I can see your point.
However, I also understand how some things can be highly offensive to people. In order to try to avoid controversial things, I will take an example that I hope will not offend others in a racial form...it is just an example to try to explain it.
For example, let's take someone who is Irish. In years past there was a great amount of discrimination against the Irish Immigrants to the Americas. Now let's say a person today, who is 5th generation American sees a portrayal of their relative who immigrated. That relative was very intelligent and started a business which today has given their family a great amount of wealth. In a book, instead of portraying them as a smart individual who started a business, they portray that relative as a foolish individual who lost everything and died in a gutter. Even though it was long ago, it offends the family members today tremendously. It also can be seen to imply things about the family today, their family business, and the quality of those people in the family business.
It's vastly different, but it shows how things that are about the past in another place can still be offensive to those that are here today in our modern times.
It is important to recognize when something is offensive, and to try to not offend others. It is normally considered polite to not go out and offend others on purpose.
Now, from what I've seen, the item that is thought to be offensive by some of a specific heritage are not necessarily seen as offensive to everyone of that heritage (which I think could be controversial in and of itself). Those that are offended are pushing for certain things, but those same things they are pushing for may be contrary to what others of that same heritage think.
Which is why I think that there may be some things that need to be done, but by those who are part of the heritage that it affects and which it could be seen as offensive. Instead of just jumping into it blindly though, they should probably try to get or gauge the thoughts of ALL sides of that community, because by doing what one thinks they should do, it may just affect another in that same group in a bad way or offensive way. Talking it over among those who are in those groups and letting them decide the best way to be less offensive or non-offensive to them may be the right way to go about it rather than those who are unaffected by it overall.
