Yes, Megan Mcardle did just say that the Supreme Court was illegitimate. And to complete the Trifecta of Incendiary Topics, she dragged Israel into her discussion of abortion and slavery.
Pushing aside all the verbiage, McArdle believes that abortion is a matter of passing a law that makes abortion legal before the fetal cells become a person and illegal after. All further stupidity flows from this. Judging by this and her explanation of the political process, I'm guessing McArdle knows absolutely nothing about the government, quite an achievement considering what she does and where she lives, and isn't exactly sure about reproductive science either.
McArdle is perfectly understandable as long as you realize that all you are getting is the passing thoughts of a person who sees no need to think when she has such fine instincts.
ADDED: No, McArdle, you're wrong. Try looking up facts instead of pulling them out of your ass.
