Inescapably Inseparable?

Rep: "Don't ask anyone else that."
Jeff:  "I suspect that thinking people from New York to California have considered it."
Rep:  "But whomever they can pinpoint as having said it they'll call an extremist and they'll  be coming after him or her with a padded cell at the ready."
Jeff:  "Who's this 'they?' "

Rep:  "Caucasians, Asians, Hindus, Semites, blacks, everybody important as populations in  the world --"
Jeff:  "And they're all represented right here --"
Rep:  "-- barking about their cultures and pretending to glorify and maintain them -- for example, the contradiction of the Caucasians and blacks here.  In other countries of this Hemisphere, there are blacks, Indians, and Mestizos openly identifying as Caucasians, but the blacks and Caucasians here pretend to be in constant conflict --"

Jeff:  "Why do you say 'pretend?' "
Rep:  "Because of those centuries of that unique 'Peculiar Institution' between them they can not conceive of having completely different identities.  Our country could not withstand it; enemies would take advantage of our strong separatism and march right in.  Half a handfull of blacks  refer to Swahili as their cultural language, but the masses of them think it's a joke.  In reality, these blacks are of an English world.  Their riots are nothing more than their swan-song, their one-word footnote, extinction, to their paragraph in the continuing volumn of American History.  Their extinction can not be stopped."
Jeff:  "I don't understand . . . you say our  country, but they when you refer to the blacks -- aren't you one . . ?"
Rep:  "I'll just say that the 'they' I told you about when we started talking will be coming for you in about three minutes."
