I'm not sure it's only the Democratic Party that has a death wish.
We didn't get as far as we have without an awful lot of Americans buying into a fantasy world that, when the stardust is removed, is about some pretty nasty stuff, centering on the destruction of the legacy American culture by all means possible.
I still see many, many people who sign up for their own auto-da-fe', I'm afraid, and do so believing they are thereby "good people" and furthering some kind of benign social evolution. Unless the American Right gets down to business with the propaganda arms that have created this popular mind-set we are just whistling past a graveyard that contains our own bones.
