Often strictly defined as a literary genre or form, though in practice it is also found in the graphic and performing arts. In satire, human or individual vices, follies, abuses, or shortcomings are held up to censure by means of ridicule, derision, burlesque, irony, or other methods, ideally with the intent to bring about improvement. Satire is usually meant to be funny, but its purpose is not primarily humour as an attack on something the author disapproves of, using wit. A common, almost defining feature of satire is its strong vein of irony or sarcasm, but parody, burlesque, exaggeration, juxtaposition, comparison, analogy, and double entendre all frequently appear in satirical speech and writing. The essential point, is that “in satire, irony is militant.” This “militant irony” (or sarcasm) often professes to approve (or at least accept as natural) the very things the satirist actually wishes to attack.
