Great links! What a scoop.
And it has been audio revorder too (I kinda like that format):

This kind of ammunition should seriously make any well read marxist out there bend over backwards and dive his head into his own, well, oricifice back there. I think that commies are mostly people motivated by a feeling of being maltreated. Marxism is the trick to make them blame “rich people” (or jews or whatnot). Those feelings urgently need to be redirected towards “forceful people” (i.e. statists).
