Several years ago when Rush Limbaugh got busted for doctor-shopping to feed his Oxycontin addiction most of the commentary focused on his hypocrisy: wanting prison for addicts but trying to stay out of jail himself.
Just out of curiosity I looked up Oxycontin in the PDR (Physician's Desk Reference) and discovered that one of the listed side-effects was "abnormal thoughts." Given the enormous quantity of Oxycontin he apparently consumed perhaps he had so many abnormal thoughts that it would be reasonable to assume he suffered from "abnormal ideology."
Ridiculing Limbaugh is the best antidote and perhaps this approach might bear fruit.
