Who are the sullen peoples and how are they characterized of the white man's burden?

The "sullen peoples" are often described as indigenous or colonized populations who resist the influence of the colonizers. They are characterized by their perceived resentment, defiance, or lack of gratitude towards the colonizers who see themselves as burdened with the responsibility to civilize or "help" them. This term reflects a paternalistic and problematic view that places the blame on the colonized for not accepting their subjugation.
