I am a huge fan of George Lakoff. Have been since the early 80s, so there.
We progressive types have long had to suffer under the fact that the right had seized the term. Left has long connoted the sinister. (I am ambisinistrous.)
With the reverend Dr. Wright in the news, and with the Right ignivomating his name on a 24/7 basis...I believe it is possible to use their own vitriol to burn their own ass.
There is a way to make it go against their better interest to bring up the name. Before long, they will be yelling "move on!".
