Be it religious or political I thought that this would be a good time to remember what Propaganda is and how it is delivered so that we don’t succumb to it either at the polls or in the pews.
Assertion is commonly used in advertising and modern propaganda. An assertion is an enthusiastic or energetic statement presented as a fact, although it is not necessarily true. They often imply that the statement requires no explanation or back up, but that it should merely be accepted without question. Examples of assertion, although somewhat scarce in wartime propaganda, can be found often in modern advertising propaganda. Any time an advertiser states that their product is the best without providing evidence for this, they are using an assertion. The subject, ideally, should simply agree to the statement without searching for additional information or reasoning. Assertions, although usually simple to spot, are often dangerous forms of propaganda because they often include falsehoods or lies.
