Polemics is the practice of disputing or controverting religious, philosophical, or political matters. As such, a polemic text on a topic is often written specifically to dispute or refute a position or theory that is widely viewed to be beyond reproach. Sometimes the word is used more widely to mean a work in which the author takes a stand on a controversial subject, such as abortion or religion, without it necessarily being against the 'norm'.
"Classic examples of polemics include John Milton's Aeropagitica and Thomas Paine's The American Crisis."
