What is propoganda used for?

Propaganda can serve to rally people behind a cause, but often at the cost of exaggerating, misrepresenting, or even lying about the issues in order to gain that support. While the issue of propaganda often is discussed in the context of militarism, war and war-mongering, it is around us in all aspects of life. At times of war, or build up for war, messages of extremities and hate, combined with emotions of honor and righteousness interplay to provide powerful propaganda for a cause.
