Roe v. Wade was not the product of a consensus among the American people -- instead, it was the product of a very liberal court that created a so-called right out of thin air. If Bush Sr. hadn't gaffed with Souter, we'd be one justice away from eliminating that anomaly of a decision. As it stands, my hunch is that two of the libs would need to be replaced.
I for one don't buy this notion that conservatives here are selling -- i.e., that there would have to be a "major opinion shift" in this country to outlaw abortion. I believe it's actually a closer call among the population than 30 years of baby killing has led far too many "defeatists" to believe.
Your mistake, Kryp, is in thinking that anyone making the argument you cite is a conservative. They are disrupters, pure and simple.
