Right wing theory vs left-wing science??!! Have any of you kids ever read actual left-wing stuff? Theory, theory, theory.
Go and read serious left wing things from a world socialist website or even Lenin's works. It is at about the same as the old theological debate about how many angels can dance on the head of a pin.
The Soviet Union with all its horrors was created by a bunch of intellectuals. In the end, the only non-intellectual Bolshevik, Stalin, was left standing.
See any liberal arts curriculum involving political philosophy for more examples. The left is just as theoretical as the right, if not more so.
As for quoting Monbiot on the intelligence of people? What next? Hitler claiming that Aryans are more intelligent than Slavs? Staling calling all Capitalists stupid for not understnding Lenin? Bakr al-Baghdadi calling all non-Muslims stupid because they do not understand the Koran?
Calling a whole group of people less intelligent because of their political beliefs is really the worst kind of bigotry. I can well imagine that that particular snob would do this, yes. George Monbiot is one of the most radical columnists alive, he is a nutcase.
