The term "dumb blond" is considered offensive and derogatory. Instead, one can use synonyms that are more respectful and appropriate. Terms such as "fair-haired" or "golden-haired" can be used to describe a person with blonde hair. Other words like "naive," "uninformed," or "gullible" can describe someone lacking in intelligence or common sense without being tied to a specific physical characteristic. It is important to use language that is inclusive, respectful, and does not contribute to harmful stereotypes.
