You know, my main problem with "Intellectuals" (and I use the section on Marx as required reading in my West. Civ. classes) is that PJ HIMSELF is guilty: he admitted to having a mistress all these years. So it blunts his charges of "hypocrisy" a great deal.
That's interesting -- I didn't know about that. However, it's only hypocrisy if Johnson had made a big deal out of "family values" or traditional morality. Although I cannot claim to have read all of his work, my impression is that he largely concentrates on "big picture" conservative issues, dealing in power, liberty, and the struggle of democracy with totalitarianism. I never thought of him as a "social conservative."
