It's just like the liberal racism that plagues the nation. Only certain minorities (conservatives) are its targets, and any guy who gets in their way will find himself under siege.
Insulting women by minimizing their accomplishments if they hold to conservative ideas is the same tactic the Far Left has used against minority men for decades. How seriously do they take the intellectual giants among them who articulate conservative ideas: men like Dr. Thomas Sowell, Justice Clarence Thomas, Dr. Walter Williams, and numerous others who have significant accomplishments, but who do not subscribe to socialist economic theories or the "living constitution" judges who wish to legislate from the bench?
Well said and as the three great thinkers you mantioned are articulate, so is Sarah Palin.
