No, I can't really tell you, it's all in my view at this point just whatever comes handy to declare your enemy as being doubleplusungood and beyond the pale.

To take the best personal example I have, in my lifetime, since I became politically and socially aware in the very early '70s, "racist" meant something, something effectively concrete, something real and observable. Now can mean something as anodyne as disagreeing with an opinion or position of Obama's.
