The surest way to take away the rights of a group is to conceive of them in the abstract, as an amorphous blob rather than a collection of individual persons.
The moral and the political are twisted together in all this like a torqued Moebius-strip: we define our political duties toward others or our rights of expectation from them in terms of the highest moral values and obligations and principles conceivable to us. But these highest moral values etc. are themselves ideologically stunted things, a bonsai-ethos that has been deformed by the contraceptive culture of the democratist Many. Do human beings have a positive and universally recognizable right to be left alone as ingrown idiotes, as self-gratifying swinish consumers, as pathetic sacks of illusions and delusions? Are ultimate rights something that the least cultured and least reflective are fit to define for themselves, much less for everyone in general? Can any civilization afford to leave its most vital principles to be framed and legislated by the least philosophically aware? When a society organizes the entire thrust of its energies and institutions to mass-produce such obtuse types, and when malleable human nature makes this organized stupefaction all too easy and efficient, how can any mere exceptional individuals do anything about such a Malthusian dynamic?
But for the Jews this moral-spiritual issue raises the same societal problem it does for the Greeks: how can a man have the "right" to make himself spiritually or rationally destitute or retarded when this corrupts the whole quality of the culture that we all together need and depend on? If anyone wants a cloistered and closed-minded life, an anti-aristic life, let him either go off and live among the wolves--or else join the community of like-minded idiots that (alas) compose and define the basic terms of modern society.
