The Sins of Native Americans

Two Spirit
Cannibalism
Patricide
Senicide
Killing the Mentally Handicapped and Mentally ill
Genocide---they would time to time systematically wipe another tribe out, and would pogrom white settlements;
Slavery
Rape
Murder
Theft
Infanticide
Child Prostitution
Human Sacrifice

These are all things Native Americans historically did.
White Culture deemed all of it illegal,
If not, you wouldn't have gotten half of Western Literature.
Check your illusions.
