It lacks rigidity, which is what has lead to the various modes of constitutional interpretation (e.g., weak originalism, exclusive originalism, and pragmatism). Fairly common examples are:
Due Process of Law
Cruel and Unusual Punishment
Equal Protection
Come on, guys, some things are common knowledge, not really in need of elaboration.
quoth the framers of the constitution on the 3000+ year longstanding ban on abortion worldwide.
from the hippocratic oath to royal decrees to parliamentary laws abortion has banned since the attic period in western society as an abomination and an affront to nature (even by non christian groups such as the greeks romans, and celts)
the framers of the constitution simply assumed that the current laws (which made abortion illegal in all 13 colonies) would remain sacrosanct, and the constitution would (as intended) be a set of club rules for the union of sovereign states for when they got together as a group to discuss common issues between them.
some states had official religions, others did not, Massachusetts officially recognized "Congregational Protestant Christianity" as the state religion until 1833, which required all men to be members of some christian church. this was NOT precluded by the constitution since it applied only within Massachusetts, and had no bearing on any of the other several states.
some states prohibit the ownership of certain firearms except by special permit/license from the state. this has no effect on neighboring states thus it is not prohibited by the constitution.
some states prohibit wearing a bathing suit on "the sabbath" (which depending on your religion could be friday, saturday, sunday,, or NO day)this too is irrelevant to the constitution.
there is only one criminal statute in the entirety of the constitution and it is only to describe define and prohibit treason against the newly founded national union. this was required by the framers since there could otherwise be NO treason in their view, as the united states had previously never existed, thus there was no prohibition on consorting with the british forces. their view of law was one of liberty within a framework of law, and the presumption was, barring an existing law to the contrary, EVERYTHING was permitted until legislation prohibited it. abortion, state religions and a legal requirement that all men POSITIVELY own arms at their own expense were all well settled at the time, and only the fog of history can create the ambiguity you claim as "common knowledge"
the republicans viewed the uniuon (as they do today) as a group of sovereign states made up of sovereign citizens who are ruled by no-one save by their mutual agreement on laws set down to establish and protect the society and it's citizens. under this world-view there is no criminal act unless the act at question is FIRST declared a crime by the society and then the violation of that statute is proved to a jury of your PEERS, not a random selection of idiots who will do as commanded and rubberstamp the judge's opinion. this is why we have a republic, not a national parliamentary oligarchy
the federalists viewed the newborn nation in much the way modern leftists do, as a mutual suicide pact. once a territory joins and becomes a state,, it is till death do us part,, and the states are merely a giant mormon style harem of submissive sisterwives who serve every whim of big daddy fed and breed up the progeny who tend to the chores around the federal plantation. the federalists LOST but since egotism and authoritarianism are notoriously bad sports, they have been slowly trying to coax the union into the federalist oligarchy they wanted in 1791, but failed to win at the ballot box.
all the vague handwaving about ambiguity in the constitution presumes the constitution is a permissive document, a list of the things we the people are permitted under the benevolent gaze of our betters in washington. this could not be farther from the truth, the constitution was created as a restraint on the encroachments of government power and the tendency to slowly ease into despotism shown by EVERY government in history, no matter how well meaning at the start.
the constitution is the chain around the wolf's neck. just because you and many other fools think Fenris has learned his lesson, and thus will NOT attempt to slay Odin, eat the sun and bring about Ragnarok doesnt mean the rest of us will join you in sawing at the monster's collar. it is in the nature of Fenris to slay Odin and eat the sun, it is his Weird and his Doom. all the "good vibes" and wishful thinking in the world will not change the weave the fates have made, nor can you restrain him once he is free. the rest of us will maintain that you and your fellow hacksaw wielding members of the Popular Front for the Liberation of Loki's Children, and your fellow travellers in the Jotun's Party for Midgard's Doom are insane.
but im probably racist since all of Niffelheim is on your side, and opposition to your agenda is clearly simply a reaction to the Svartalf in Chief's pigmentation not his stated aims.
