You don't know?
Oh I know...I KNOW all right...
One marxist (you) will trust another marxist (Lee) to explain a guy IS a marxist (Lewontin) to discredit his scientific beliefs.
AND you can even go on believing to the end of time this is all an exercise ‘for the sake of science’!
Meanwhile us sane, rational, normal, conservative, folks will question YOUR motives, ideas of ‘truth’, ‘science’ and so on...ad infinatum.
