Leftist Catholics are too ignorant to even know what 'distributism' is.
Most of the Catholics that were distributists were also very conservative. Especially Hillaire Belloc who was one of the first commentators to state that at some point one of the major foes of Western Civilization would be Islam. And this was before the communists had even done their worst.
Before Belloc was born, that major foe had 1,000 years of aggresive history. To me, Mr. Belloc's economic theories were unconvincing.
