Anti-blonde
 prejudice and stereotyping is one of the most common examples of 
projection. The coincidence of anti-blond jokes and ridicule being so 
common that they're practically "normalized", combined with the fact 
that the most common hair color treatment is blonde, is too obvious to 
ignore. 
 Where does anti-blonde prejudice and desire to belittle 
come from, and why do people so adamantly deny that there's anything 
wrong with it? On the flip side, if having blonde hair means a person is
 not smart, or unstable, then why do so many people dye their hair 
blonde? 
 Why are human beings so fixated on something as superficial
 and simplistic as the color of a person's hair, especially when it's so
 easy to change? 
 What is the emotional issue that so many people have regarding this?
