My name is Melvin Martin, I'm 56 years old and an enrolled member of the Oglala Sioux Tribe of South Dakota, Pine Ridge Agency.
I am writing to express my most heartfelt belief that in the future that you (as an actor of good conscience and a strong ethnic awareness) should decline any roles that call for you to portray a Native American (aka American Indian) woman as the Hollywood film industry has a very lengthy and sordid history of utilizing non-Native American actors in Native roles, thus brutally depriving actual Native actors of the exceptionally rare opportunities to truly represent Native people on film.
Hollywood has always been destructively rife with non-Native frauds of a wide variety of ethnic backgrounds who assume Native roles and the net effect of this type of gross misrepresentation is that we as actual Native people are perpetually denied our basic humanity to the rest of the world--we are living, breathing human beings who are still very much here and nowhere near "extinct" as many non-Natives, throughout this country especially, actively believe.
Therefore, as an actual "Native American" person and one who has had to endure a lifetime of race-based indignities, I call upon you to "do the right thing" for the remainder of your acting career which I sincerely hope will be a most successful one.

But suppose the 1/16 claim is true. To me, that would put her in the same category as Johnny Depp, Taylor Lautner, Lynn Collins, and Summer Glau: a non-Indian with a few drops of Indian blood.
