Do you trust government?
Do you think Rand Paul was wrong when he said the civil rights act of 1964 theoretically goes too far when it bans discrimination in a private business? If you do then you are substantively against private property rights. Keep that in mind as you watch Broken Rainbow. Had the Navaho and Hopi been treated according to the morality and legal philosophy of a libertarian they would have been compensated for their land. Instead we played by the rules of the Neofeudalist class. Since Navaho and Hopi did not have many votes to offer they were run over. By not believing in private property and libertarianism you open the door to all manner of "sharp operators". Many of whom end up in the United States Government.
Note when watching this video that the left romanticize primitive cultures and would have you believe several obviously false things. They would have you believe had the native americans not been hoodwinked by actors in the U.S. Government and Peabody coal that they would have refused to allow mining on their land. This is a tall assumption. A more plausible reality is that the price paid by Peabody and company would have risen to market value and the Navaho and Hopi would have sold out sooner or later.
The left sees opportunity in people treated shabbily. However their eyes are always on making names for themselves or opening new territories in legal standing and representation. This is not unlike opening wide open frontier land with little competition. What would you expect? So many of them are lawyers. If they do not see a chance for recovering on your claim you will get very little love from them.
