Was I right or was I right?

Who could of guessed it? Andrew Sullivan has made his fourth post on Ramesh Ponnuru's book Party of Death (which he hasn't read) and notes that one of his readers (who doesn't sound like he's read the book either) "nails it."

Isn't it hilarious that someone who hasn't read the book could describe someone else who probably hasn't read the book as "nail(ing) it" in a description of the book? One would think that someone would have to actually read a book to be able to judge if someone else's critique of the book is accurate or not.
