It's like saying you gotta buy one if you wanna get one free. -- "Weird Al" Yankovic
Shorter conservative thinkamator:
Instead of pestering us to explain the specific dangers of the crack, or pointing out that nothing is in fact wrong with your mother's back, just do what you're told. Those "smart" people are just trying to trick you into stepping on the crack.
Really, unless he's trying to be facetious or ironic here, for a guy who actually wrote a book on people who avoid reason and logic for fanatical, uncritical thrall to "traditional imperatives", he's just being obtuse.
