What is Malinchism?

Answer 1

From what I understand, it's used by Mexicans, referring to a behaviour of preferring anything foreign over national.

Answer 2

Malinchism refers to the act of betraying one's own culture or people in favor of another, often for personal gain. The term originates from the historical figure La Malinche, who served as an interpreter for Hernan Cortes during the Spanish conquest of the Aztec Empire in Mexico. She is often seen as a symbol of betrayal by indigenous people.
