chauvinism

Chauvinism ( ) is the unreasonable belief in the superiority or dominance of one's own group or people, who are seen as strong and virtuous, while others are considered weak, unworthy, or inferior. The Encyclopaedia Britannica describes it as a form of "excessive and unreasonable" patriotism and nationalism, a fervent faith in national excellence and glory.

In American English, since the 1940s, the word has increasingly been used as a shorthand for male chauvinism, a trend reflected in ''Merriam-Webster's Dictionary, which, as of 2018, began its first example of use of the term chauvinism with "an attitude of superiority toward members of the opposite sex".
