Kia Ora Michael thankyou for your comments. Appropriation, like racism, is an act that is bound in power relationships. The ubiquity of western stories make this a non-reversible phenomenon (eg the fact that we in Aotearoa were colonised means I am not "appropriating" western clothes when I wear them). The holocaust example doesn't really wash the same way, not least because the Jewish stake in Hollywood is so high with at least 60% of Hollywoods top positions being held by Jewish professionals.  So there is a different power relationship for them in the field of storytelling. 

We on the other hand have a duty to actively protect our storytelling precisely because of the unique threat placed to pacific peoples by tourism and Hollywood who continually fetshize and misrepresent our cultures whilst simultaneously monopolising the global market.
