"Death panels" is such an excellent term. You know exactly what it means, and therefore you know you're against them. Debate over. This term more than anything else seems to have unified the opposition to the Obama health care proposals. It fuels the anger that has essentially shut down "town hall" meetings intended for the discussion of the issues.
Of course the term is inspired by a lie. There are no conceivable plans to form "death panels" or anything like them. The Obama plan, which has some bipartisan support, doesn't seek or desire to get involved in any decisions about who should live and who should die. But now we hear "death panel" repeated so often that the term has taken on a sort of eerie reality, as if it really referred to anything.
