UPDATE: Curiosity got the best of me. I went back to FB and used a name I thought FB might think is a real name and guess what? There were no problems setting up that FB account! None at all, no glitches, no provide documented proof! Nothing! This proves FB has issues with the names our Elders have given us!
I do not believe fb should be allowed to judge whether a name is real based on their opinion of what a name is. Just because Native American names aren't Mark, Mary, Johnny, Chris, etc doesn't mean they aren't valid names known to our family and friends. I thought businesses weren't allowed to treat people like this? If I went back and told them my name was Mary Smith they would accept me, but you know what? I don't want to support any company who does not see me as a human being.
