Satire is a form of writing that is meant to make fun of something the author feels strongly about. The goal of satire to be humorous to people who agree or disagree with the author. Similarly, political cartoons are another form of satire readers may be familiar with.
Satire is another way for authors to convey their opinion in a way that makes people laugh. Much like opinion articles, they are based in fact, but may also include some made-up information for the sake of humor. It also meant to more or less persuade readers, because the idea is for the person or group that the article makes fun of to laugh along with the writer.
