As an aside, their deterministic claim regarding the intrinsic quality of the cultural technology of debate rests on assumptions about the psychology of debaters - something very difficult to prove with only textual analysis of a few commentators from the 1950s (i.e. Day, Murphy, et al.).
More centrally, it may be possible to fashion a critique of Greene & Hicks on the grounds that their analysis enacts a form of technological determinism, i.e. the notion that technologically speaking, there are intrinsic ethical commitments invested in the activity of switch-side debate (namely, belief in American exceptionalism). As a counter-example, one might point out that in the 1954 "debate over debate," this strong principle of technological determinism was not found in the psychology or practices of debaters who viewed a commitment to switch-side debate less as a foundation for American exceptionalism and more as a bulwark against McCarthyism. Another, perhaps even more powerful example is Malcolm X, who embraced switch-side debate as a tool to counter American exceptionalism.
A charitable read of Greene & Hicks emphasizes the narrow scope of their study (ONLY focusing on 1954, not extrapolating beyond), thus taking some wind out of the sails of the technological determinism critique. But notice how this retrenchment move is not available to the Masseys of the debate world who cite Greene & Hicks as proving that IN ALL CASES (even in today's milieu) debate as a cultural technology reinforces American exceptionalism. This is technological determinism in full flower, and we could fashion a compelling kritik argument suitable for use in contest rounds that would isolate this move made by opponents, and make rejection of the claim a voting issue.
