Getting a Metaphorical Grip

John Hutchenson sensibly calls for a bipartisan moratorium on the use of the name "Hitler" to describe political opponents who have done something less than kill 6 million people while attempting genocide. Hutchenson specifies that changing one's mind on an issue would not create an exemption.

Hutchenson is right. Using Hitler or the Holocaust as metaphors for anything currently happening in the United States diminishes the horror of the 20th century's ultimate inhumanity. That is a horror that, as we say, should not be forgotten -- or diminished.
