Bingo.
With the pregnant daughter story it was bizarre. For liberals, actually carrying a pregnancy to term is such a rare experience they treat it like a UFO encounter or Bigfoot sighting when someone decides to have a child.
Looking at the five children and pregnant daughter, liberal journalists became unhinged because most of them have had abortions. And it would be natural for them to abort a child conceived outside of marriage. That explains some of the liberal hysteria over the Palin candidacy. They are outraged by the living example of a pro-life family.
A fit, healthy, happy working mother with five children flies in the face of all of the propaganda liberal feminists have pushed - that having children is a terrible burden, that they would never want a girl "punished with a child" (to quote Obama).
It is a post-abortion rage reaction.
