an action is objected to on the grounds that once it is taken, another, and then still another are bound to be taken, down a "slippery slope" until some undesirable consequence results. Arguing that a slope is slippery without providing good reason for thinking that it is, or when the slope clearly is NOT, makes us guilty of the slippery slope fallacy. (for example, a Canadian style "single Payer" health care system is often objected to because people believe it will lead us down a path to socialized EVERYTHING. NOTE: not all of these are fallacies. It is only a fallacy when we accept without further justification or argument that once the first step is taken, the others are going to follow, or that whatever would justify the first step will justify the rest.
