Yes and no. There have been some very long threads on race and class. But your appended Communist Love Song is an appropriate comment on those threads: they tend to go around in a circle endlessly, a circle which does not incorporate new material with each spin of the wheel*, but merely restate the general point (which I then stated again in my post). When I say it's devilishly difficult, I mean it is difficult to get the discussion to go much beyond this reaffirmation of what I believe has been established as a truism, but...
How do we move that discussion forward beyond that truism?

P.S. My parenthesis about "each spin of the wheel" reflects my huge admiration for the first 125 pages of Volume 2 of *Capital*, pages which go round and round reasserting a tautology, but with each reassertion incorporating more of the "feel" of the capitalist dynamic.
