"Do you ever wonder how communism could last for 70 years in Russia? Surely there was plenty of evidence, for decades, that the system was failing: food shortages, declining life expectancy, increased infant mortality, low standards of living, primitive hospitals, and sanitation facilities lagging far behind those in Western Europe and America — not to mention pollution far worse than in the West. But to diehard communists, the facts did not matter. All the observable negatives of collectivism were trumped by ideology. The same is true of the ideology behind global warming."
