The sentence that shows the most bias is:
“What good man would prefer a country covered with forests and ranged by a few thousand savages to our extensive Republic, studded with cities, towns, and prosperous farms . . . ?”
This statement conveys a clear bias against Indigenous peoples by referring to them dismissively as "savages" and contrastively portraying their existence as inferior and less desirable compared to the "extensive Republic" characterized by civilization and prosperity. This language demonstrates a prejudiced viewpoint that devalues Indigenous cultures and reinforces a notion of superiority of the settler society.
