Persuasive writing is, literally, writing for the purpose of persuasion. This is common commercial and political practice. It's similar to advertising techniques, directed at a single goal of persuasion to act in a particular way. In politics, it's intended to influence opinions and voting preferences. It's intended to force the reader's logic in favor of the view of the author.
Examples of Persuasive Writing:
|Ayn Rand: Works in favor of free market capitalism and social values.|
Noam Chomsky 'Manufacturing Consent':Works in favor of liberal reform of media values.
Michael Moore: Media production based on supporting protection of consumer rights and interests.
