I wish he would have unpacked strange insinuations like the following:

... the same kind of leap of faith which Yoshie Furuhashi reminded us was the great French mathematician Pascal's definition of Christianity. ... As is clear from discussions on this List, some who might define themselves as Marxists also turn out when scratched to be made of different metal.

Doe[s] he mean to imply that Marxism is just Christianity in another guise?

No, he means that, just as Protestants and Catholics are essentially Christian, so Marxists and Capitalists are what De has called "Industrial Cornucopians". Both are Industrial-Revolution ideologies, and both believe in economic growth and productivity. If anything, "real" Communism has been more socially and environmentally destructive than Capitalism when it has embarked on mad dashes for progress and development.

Can the last politician to go out the revolving door please turn the lights off?
