Explain the similarity between the English attitude toward the Irish & their attitude toward Native Americans?

Primitive, savage people who worshipped false gods and who would murder you and your family at the drop of a hat. They spoke an incomprehensible language, were often half-naked, and their children played in the dirt like little beasts. They had no idea how to farm properly and made little use of their holdings. They liked strong drink but could not hold it. They were still arranged in tribes like the ancient Britons.

I could not find an appropriate image for Ireland at the period but the standard peasant home in Ireland and in the west of Scotland was a low shed of drystone walls sealed with mud and dung and roofed with turf. It would have a floor of puddled clay and rushes or rush mats on the floor. It would be shared with with the animals in cold weather. Most people lived in small villages of about half a dozen cottages.

Settlers have a different view of native populations to those of explorers or even the Administration appointed by the home government.. They are generally not particularly interested in the culture and history of the peoples who land they covet, they just see them as an obstacle, therefore they will always find negative ways of describing the natives. To do otherwise would be to question the whole right of the Settler to even be in the new land.
