Demonization is when someone is portrayed as very bad or evil. It's like in cartoons or fairy tales when there is a really mean witch or a scary monster that wants to hurt the good characters. Sometimes in real life, people are treated as if they are very bad and are blamed for things they didn't do or are punished more harshly than they deserve. It's important to remember that demonization isn't fair or good and we should always try to treat others with kindness and respect.
