History Textbook shaping the way of seeing Native Americans

This online textbook put the Native Americans in a bad light. From looking at different text through out this history book the Native American came across very hostile to the white settlers, but in the textbook they were sure to say "Again the savages were pursued without mercy." (pg.32). This quote was found in different parts of the textbook but in different wording. When looking up the word "savages" many text around the word was about how the indians killed some white people. This would shape my view point of Native Americans by thinking they were all very hostile and vengeful, even though I'm sure there are some peaceful tribes.
