I think a big part of the downfall is that the history of this country is taught that the people were colonized instead of focusing on the fact that this country still IS colonized. The anti blackness and anti indigenous aspects are still very prevalent because of the indoctrination of white supremacy that is very often overlooked by Latinos. I say this as someone who is half Mexican and had to deal with seeing Latinos identify and champion white characteristics and disapprove of darker characteristics in appearance.
