But that doesn’t explain why you persist in using the term Marxist, especially when you admit that the term itself has no resonance for younger readers. Indeed, the article from which you draw your image does not use the term Marxist at all, and it saves use of the word Communist for one or two minor ‘influencers’ in relation to the 1970s.

No fan of Corbyn, but if the FT isn’t labelling him as Marxist, then perhaps capitalism can sleep easy tonight. ;-)
