The Freedmen Saga Continues

The Freedmen are now suing in tribal court over the election to kick them out of the tribe. I'm sure it will go to Federal court next. Can we please, for the love of God, stop pretending this is about "Indian blood"? This controversy doesn't have a damn thing to do with "Indian blood" and everyone knows it. If it was, then why couldn't we just allow the Freedmen to submit secondary sources (like the Cherokee Census, for example) to prove their "Indian blood," since they were denied the opportunity to list blood quanta on the Dawes Rolls?
