How do stereotypes affect people?

The novel, “The Chrysalids” by John Wyndlham start after a nuclear war where lands are contaminated and too hazardous for people, animals and plants to live on. Most of lands are polluted except one land, Waknuk. The protagonist is David Strom who lives in Waknuk and has special telepathic abilities. David is not the only one who can use telepathy. Some children can share their thoughts using telepathy inside their head. Because of the radiation from the nuclear war, people are left disfigured. For example, some people have six toes and an extra arm. People are afraid of tribulation because it is a symbol of nuclear war, so they discriminate the people who are affected by tribulation. People want to eliminate all of symbols of the war. People who are affected by tribulation are banished to the contaminated land called Fringe. David and his friends know about this, so they try to escape to Waknuk. If other people know about their abilities, they would banish them. People who had tribulation felt anger or fear because they lost their human right and life as normal people. Humans can have prejudice, so we need acknowledge difference and break prejudice. This novel shows that stereotypes can menace people’s life.
