But there's more going on here than simply the yowl of wounded meritocrats. In fact, Sarah Palin presents an existential threat to liberal ideology -- which holds that in order to be truly liberated and powerful, women must have every kind of abortion right imaginable. That women are struggling uphill in a sexist and unfairly capitalist society -- where government is required to level the playing field and enforce true "equality" between the sexes. She's a walking rebuke to the victimology that's the left's stock in trade.
To see a woman -- and a Republican woman, at that! -- breaking all the "glass ceilings" without the help of the government or the approbation of the feminist establishment is just too much. It's a threat to their world views (not to mention to the Democrat Party). It suggests that government isn't always the answer . . . and that the self-appointed spokesmen for women's rights aren't just wrong -- they're irrelevant.
Hence, the venom.
