First of all there's nothing "practical" about imagining that civil rights leaders were robots, I mean really... what the fuck? Its a completely pointless (definition: the opposite of practical) thought-experiment and its sort of weird. One point I will make is that its based on a Lutheran/Protestant outlook. Now what was that the Spirit of... hmmm... trying to think here... oh yeah, it was basis of The Protestant Ethic which was undoubtedly involved in the historic development of contemporary capitalism as well as, and this is less recognised, it formed the ideological basis for Soviet Communism through the medium of, you guessed it, the "iron laws of historical materialism".
Secondly, and before you say "but that's a psycho-social argument and I am a robot-man" I have to point out that trying to carve up psychology and sociology (or economics or whatever) into completely compartmentalised disciplines is completely pointless. True under certain circumstances economic/sociological variables are predominant and under others psychological variables are and its extremely important to be able to grasp which one should be laid emphasis on - hence why I was complaining a while ago about the tendency to psychologise the crisis through dubious applications of psychiatry to people one has never even met - but all of these things have to be considered together, in their "totality" as Marx might have put it. Any other way of looking at things is at best a retreat in dualism with all the religious overtones therein, at worst an adherence to complete scientific dogma.
