A bigot is a person who is intolerant of opinions, lifestyles, or identities that are different from their own. Mostly, the person's opinions are based on prejudice. For example, an outspoken member of a political party who blocks those with opposing views, would be a prime example of a ‘’bigot’’.
The origin of the word bigot in English dates back to at least 1598, via French. It started with the sense of "religious hypocrite", especially a woman.
