"The concept of Bigotry can have slightly different meanings in American and British English.
In British English it refers to a state of mind where a person is obstinately, irrationally, or unfairly intolerant of ideas, opinions, or beliefs that differ from their own, and intolerant of the people who hold them.[1][2]
In American English, the term can be used similarly; however, it can also be used to refer to intolerance towards a group of people in general based on their group characteristics such as race, religion, national origin, gender, disability, sexual orientation, and socioeconomic status.[3][4]"
