However, "dehumanized" was not a very good choice of term for the exact attitudes I had in mind, which I think indeed have little historical precedent and, and which don't really correspond to the traditional patterns of exercising crude power by higher-status groups and individuals, being a rather peculiar aspect of the present situation.

Dear Vladimir, must as I hesitate to offer you any assistance in your presumably shady-looking intellectual enterprise (as frankly I've grown to dislike you quite a bit, period).... the term you might've been looking for is "http://en.wikipedia.org/wiki/Biopower".
