What is the saying about don't trust a red head?

The saying "Don't trust a redhead" is often rooted in stereotypes and folklore that suggest red-haired individuals are fiery, unpredictable, or temperamental. This notion can be traced back to various cultural beliefs that associate red hair with strong emotions or rebelliousness. However, it's important to recognize that such generalizations are not based on fact and can perpetuate unfair biases against people with red hair. Ultimately, trust should be based on individual character rather than hair color.
