“This fallacy is the generic form of which other appeals to emotion—the Appeal to Fear (see here), the Appeal to Pity (see here)—are subspecies. The fallacy is identical in all cases: the proponent tries to argue his case not by appeal to the facts, but on the strength of his and others’ emotional reactions to the facts. It is a fallacy for the very same reason: my feelings about the facts of the matter are simply irrelevant when it comes to their truth or falsity.”
