Your own quote of Lewontin denies this parodic mischaracterization. Lewontin specifically accepts that races evolved and that such differences as exist are genetic.
What society DOES with that concept is another matter entirely, but I am strictly speaking of the biologic issues. Lewontin and Gould used half-truths and misrepresentations to bolster their political views through "science." If you contend that they are and were great scientists, so be it. Whatever their accomplishments in research may have been is--IMO--subverted by their politics.
Perhaps you hadn't heard, but they attacked E.O. Wilson repeatedly for his sociobiology, and circulated petitions to stop discussion of IQ and genes on the Harvard campus. Nice heroes you have...I guess Lysenko is on your list also.
