‘Democracy’ needs to be understood in the context of the rule of law and a Constitutional Republic.
Many things are not subject to ‘consensus,’ inalienable rights primary among them.
I never agreed with the term "inalienable rights" because there are so many global examples of rights upheld or taken away by government.
I like your quote's definition better. They are what the bylaws for our governments forbids legislation over.
"Inalienable rights" only in the context of the American Constitutional Republic, where there exists a ‘core’ of rights that although not absolute, are nonetheless not subject to being taken nor bestowed by any government, constitution, or man.
All acts of government are presumed Constitutional until a court rules otherwise. Over the decades and centuries, however, there manifests a body of acknowledged and settled case law (judicial consensus) which clearly sets the boundaries of what acts are and are not Constitutional.
It is incumbent upon lawmaking entities, therefore, to recognize and respect those boundaries, and to enact measures in good faith that conform to Constitutional case law.
In recent years, unfortunately, with regard to a significant number of conservative lawmakers, that has not been the case. And these conservative lawmakers, as well as those who agree with them, have grown increasingly frustrated as the clearly un-Constitutional measures and policies they advocate are appropriately invalidated by the courts. The illegal racial profiling policy by the Maricopa County SheriffÂ’s Department in Arizona is yet another example.
