White Savior

A “white savior” refers to a white person who is depicted or perceived as rescuing or helping non-white people in a way that is often seen as self-serving, patronizing, or reinforcing stereotypes of racial superiority. This concept is frequently criticized for perpetuating a narrative where people of color are depicted as helpless or inferior, requiring white intervention to achieve progress or success.

Green Savior

A modified, upgraded version of a white savior - basically a Chomsky/Zinn reading America flagellant who props up indigenous cultures as unassailable paragons of humanity and believes the only way to solve environmental crises is to bring down the entirety of modern, industrial civilization and return all the land to the roughly 2% of the world's population that is indigenous, etc.

People who claim opposition to electric vehicles, solar/wind power are clearly nothing more than green saviors who won't be satisfied until the whole of industrial civilization collapses and the earth is rid of 98% of humanity.
