Besides being a concept that was used in ancient times as a method to brand the bodies of slaves and criminals with a red-hot iron in order to exhibit those people, stigmatization appears as an attempt to marginalize or to classify people due to specific characteristics they have, despite having the same logical grounds in social sciences, primarily in sociology and psychology. Throughout the history, individuals, who were marginalized or considered as people to be kept away from, were always stigmatized through the opinions of the people, and not always necessarily with a red-hot iron, in many societies. The categorization and classification of people appear to be a pattern of behavior that the majority, consciously or unconsciously, have.
