You Can Make a Career Out of Saying Stupid Things About Karl Marx
For a fine round-up of the standard nonsense and its precise, well-documented refutation, there is now Marx Myths & Legends.
Frankly, I doubt it will do one bit of good. This is a matter in which total ignorance tends to be quite proud of itself.
It's a magnificent resource, even so. (Thanks to the new site Continental Philosophy for pointing it out.) I am particularly glad to see that the site includes Christopher J. Arthur's classic paper "Hegel’s Master-Slave Dialectic and a Myth of Marxology".
The notion that Marx drew on Hegel's analysis of"lord and bondsman" relationship (as it's also called, in the Baille translation of the Phenomenology) is one of those things you hear so often that it's kind of shocking to learn that there is no real evidence for it.
As myths go, of course, that one is not so pernicious as the efforts to present Marx as an architect of despotism.
But the fact that the site includes Arthur's paper is evidence of its high standard of seriousness.
