OK, I'll agree that the DoI is not a statutory document and carries no legal authority in that respect. But I disagree that those "fundamental disagreements" were not part of a process of adducing the essence of the DoI into a framework of statutory law to be our Constitution and BoRs. The basic principles of the DoI are reflected throughout those two documents. The poetry of it may not be law itself but certainly its moral weight and probity still provide sound rhetorical guidance for understanding the genesis and purpose of the latter two.
you are still trying to make me admit to a constitutionally guaranteed right to life.
I shall not, since there isn't, so you might as well quit it.
I will say that there is an unenumerated natural right to life (cf: the ninth and tenth amendments) which is moderated by the fourteenth amendment's due process clause.
That does not help you in this case, as in this case the statutory processes legal and ruling in the state of Florida have been duly enacted and observed.
