Of course, your opinion is not unreasonable.  Because the harsh reality is that today's natives never had chance to prevent colonial history's affirmative acts that sterilized their ancestors' traditions and land culture.  That separated their near ancestors, and thusly theirs, from indigenous ties to 'Aina, which modernists simplistically view as mere "religion."  Malcontent?..perhaps.  Disingenuous?...probably not, but instead circumstantially born into ignorance of their full identity and roots.  Modernists commonly focus instead upon America's natives as drowning their sorrows in booze and insecurities in drugs.  So, you say here at TMT they've nothing positive to contribute to society and progress?...I disagree.
