Much like Godwin's Corollary, but involving the phrase "slippery slope". The person stating in an
argument that something is a "slippery slope", the discussion is ended and the mentioner has
lost the
argument.
While on a forum discussing "mandated vaccinations",
Jim said it was a slippery slope to
death panels. Everyone else recognized this as a sign that no rational discussion was going to occur and the discussion was ended. Jim is an
asshole. Barbara hated it when a discussion was ended via the LDB Corollary.
