The right often complains about the ease with which words like "racist" or"fascist" are thrown around these days. But, when it comes to their approach to the left they're happy to throw around words like Marxist or communist.
And the funny thing is, that Marx and Engels were pretty rare amongst thinkers in that they offered a one sentence summary of what they stood for:
"In this sense, the theory of the Communists may be summed up in the single sentence: Abolition of private property."
Corbyn supports private property.
