tbf whilst I completely agree the "tankie" label doesn't fit Corbyn and his average supporter particularly well, one of the more interesting properties of Corbyn is his ability to maintain very good relationships with both the "Stalinist" and "Trotskyist" factions of the British radical left (who tend to hate each other and have little more regard for the Labour Party)

I think the "tankie" description is pretty fair when applied to likes of Seamus Milne and Andrew Murray, though of course Milne stopped being the Guardian's comment editor to work for Corbyn and Murray hasn't written for them since 2013.
