I'm 1/8 Indian, I can call myself Indian or Native American if I want.
Dixie if your 1/8th American Indian and you live in a area with a Indian owned casino i think you might be able to collect from it. I forget the details though, and i could be wrong about that but i think i remember reading something about it at one time.
I remember Donald Trump was bitching about how little indian you had to be to get a Casino license years ago for a Indian owned Casino and he infamously said :
"THEY DON'T look like Indians to me and they don't look like Indians to Indians"
