I do agree, what the missionaries were preaching, was as offensive to them, as what atheists or Luciferians spout off to Christians, but meh, that is all part of the will of the Creator.
"Before any final solution to American history can occur, a reconciliation must be effected between the spiritual owner of the land - American Indians - and the political owner of the land - American Whites. Guilt and accusations cannot continue to revolve in a vacuum without some effort at reaching a solution. "
