Parade of Horribles - As A Rhetorical Device

As A Rhetorical Device

A parade of horribles is also a rhetorical device whereby the speaker argues against taking a certain course of action by listing a number of extremely undesirable events which will ostensibly result from the action. Its power lies in the emotional impact of the unpleasant predictions; however, a parade of horribles can potentially be a fallacy if one or more of the following is true:

• The action doesn't actually change the likelihood of the "horribles" occurring. The "horribles" could be unlikely to occur even if the action is taken, or they could be likely to happen anyway even if the action is avoided. This is an appeal to probability, and can be viewed as a non sequitur (logic) insofar as the action has no causal relation to the "horribles".
• The argument relies solely on the emotional impact of the "horribles" (an appeal to emotion).
• The "horribles" are not actually bad.

A parade of horribles is a type of hyperbole, because it exaggerates the negative results of the action, arguing that "If we do this, ultimately all these horrible things will happen".
