I don't believe in astrology, but I think the DUmmies post is a classic example of how opinion influence astrological "readings"
So, based on their astrological chart, both Sarah Palin and Glenn Beck are either inspired to do God's work (amazing that a DUmmy would use such language) or they are megalomaniacs. Because in the DUmmies world, it is impossible that either might be striving to do God's work, they are megalomaniacs.
I don't get the intellectual dominance section of the DUmmies post, other than to think that Glenn Beck argues circles around DUmmies, and the Sarah Palin/Queen comment could just as easily be interpreted as her being a natural leader.
