...redefine morals and ethics DOWN by giving both of those words little value in their limited vocabulary.
I'd particularly feature this statement. I believe this is a consequense of taking an "objectivist" view of ethics and morality. A part of the fundamental discrepancy between American political philosophy and much of libertarian thought is that the former is based upon self-evident truths (including natural law theory of law) while the Ayn Rand style libertarian tries to look only at cause and effect (something unnatural and counterintuitive and prone to resistance and breakdown even in their own minds).
Have you considered the potential ramifications of making ethics and morality subjective?
