scapegoat
A "scapegoat" is a person or group that is unfairly blamed for problems or negative outcomes. This term originates from an ancient ritual in which a goat was symbolically burdened with the sins of the people and then sent away, representing the transfer of guilt. In modern contexts, scapegoats are often used to divert attention from the real issues or culprits.
In various situations, such as in politics or social dynamics, individuals or groups may be targeted as scapegoats to relieve others of responsibility. This can lead to unjust treatment and can perpetuate stereotypes, as seen in historical events involving minorities or political opponents.
