Peak Wingnut Theory
By Henley on the NAMBLA wing of the Republican Party. Cf. also here and here and here.
IIRC it was a calumny done to Erick Erickson that caused the development of the farcical Online Integritude project. I’m sure somehow thinking that a 10 year-old could have an “affair” with an adult could also be redefined as representing serious integrity by the relevant wingers. Erickson has written plenty of howlingly dumb things before, but this might be a low that can never be surpassed.
