As someone who has always been drawn to animals and nature, I was naturally drawn to and curious about the Native American cultures. Went through a long phase where I read many period books about what everyday life was like, how they lived, hunted, made clothes, etc. All of it was fascinating to me. I truly enjoyed learning about many of the native cultures. When my mom was doing geneology work, she discovered we had a Potowatomie in our background. I will admit to thinking it is pretty 'cool' even though I in no way consider myself to be Native American. I am sorry that you face racism even in today's 'enlightened' age; we are all equals, and should be judged as individuals. I try to do that in my own life. But, isn't it better to think it's 'cool' to be a fraction Native American, than to be ashamed and try to hide it?
When someone asks about my ancestry, I generally tell them German/Irish/Welsh. But I do think it's cool to have a native ancestor, way back, because I admire their closeness to the earth and it's inhabitants. It's part of my family history, and I'm proud of it.
Just my .02.
