Settler: “A person who settles in an area, typically one with no or few previous inhabitants.” (from my Apple dictionary and from google def, not sure what the source is?)
Colonialism: (1) “The practice or manner of things colonial” and often serves as a synonym for “provincial;” (2) “The colonial system or principle. Now freq. used in the derogatory sense of an alleged policy of exploitation of backward or weak peoples by a large power.” (from the Oxford Dictionary of English)

No or few previous inhabitants? Wow, that’s a convenient myth that erases all the people who happened to occupy the land you were on before (like all First Nations in America).
And gotta love the “alleged” and “backward or weak people” in definition (2) of colonialism.

I think my faith in dictionaries has just about hit rock bottom…
