Bigotry refers to an intolerant and unreasonable attitude or behavior towards a particular group, based on prejudice or hatred. It involves making unfair judgments about people or things based solely on their characteristics, such as race, religion, nationality, gender, or sexual orientation, rather than considering individual merits or differences. Bigotry can manifest in various forms, including discrimination, harassment, and violence towards those who are perceived to be different from the bigoted person or group.
