Sara Palin and The Left's Status Anxiety

Why do 'the good and the great' despise Sara Palin so much?  After all she's like tens of millions of other moms with similar backgrounds and beliefs, she's a fairly conventional conservative politician rising up a fairly conventional ladder of PTA, City Council, Mayor, Governor?  Why the shrieking hatred?  Shannon Love explains that La Palin gives the left elites a monster case of status anxiety.  Money graf:

That is why leftists see Palin as a genuine and significant threat of unusual magnitude. In the emotional thinking of leftists, she is a personal threat to everything each individual leftist has attained in life. They feel a sincere, visceral sense of danger about her because she attacks the very core of their egos. They feel the same hatred towards Palin that the European upper classes felt towards the upstart middle-class. They feel the same hatred that poor whites felt towards non-whites. They feel that way for the same reasons. If she succeeds, worse, if she is right, then they become nobodies.

And there's a slow train coming up around the bend....
