Why some ignorant people think that all Mexicans are short and have dark skin?

It is like, to think that all Americans are white,blond hair, and blue eyes which is NOT TRUE AT ALL. I have lived in many parts of the country and I have met people who have English last names and call themselves "whites" and are not blond ,don't have blue eyes and many of them have brown skin and Iam not talking about African Americans. Also I have seen many girls who dye their hair blond... does that make you white? Because

the Steriotype for "white" is pale skin natural blond hair and blue eyes. I THINK ALL AMERICA NOW IS MIXED

In Mexico you find all races too but some ignorant Americans get really surprise or even piss off when you are white and Mexican. Like if the "white" people in the USA are white because of their Native American heritage and not European. I never seen a PAPAGO with blond hair and blue eyes. There a lot of nativeamericans too but they were pushed aside to not get noticed. Most of the Mex people who inmigrated to the USA are the poorest peopl

It's called a stereotyping. Stereotype production is based on:

Simplification, Exaggeration or distortion, Generalization, Presentation of cultural attributes as being 'natural,' Unshakeable belief in stability of stereotype, Racism, sexism, and other forms of discrimination, Historical factors, Guilt by association, etc.

Stereotypes are seen by many as undesirable beliefs imposed to justify the acts of discrimination and oppression. It is thought that education and/or familiarization can change these misbeliefs. Other negative effects are: justification of ill-founded prejudices or ignorance, unwillingness to rethink one's attitudes and behavior towards stereotyped group, self-fulfilling prophecy for both stereotyping and stereotyped group (White people treat black people in a more hostile way due to being afraid of them. Black people accordingly react more aggressively, thus confirming the stereotype...)
