Anyway, back on topic: commies who haven't read Capital - is it all about the Manifesto, or are you going on secondary sources?
I have actually read the Manifesto and the 14h Brumaire (?)
I suspec that a lot of the Communists I knew growing up (mostly old men) had actually read much of Marx at all - most of them had left school at 14, though some would later educate themselves/miners reading rooms etc.
