The original text is basically useless. They're more like a mission statement rather than directives. They set up broad aspirations, but the implementation has to be aggregated over literally millions of pages of judicial decisions.
Even lawyers with extremely different ideologies will give you convergent answers in a lot of cases, even when those answers conflict with an apparently obvious reading of the original text. Explaining that would require drilling down into details of thousands of court cases -- like reading a complex proof of a seemingly simple theorem.
I don't like that any more than you do. It's not mathematics, and even when given all the details, I usually find their inferences laughably bad -- even when I agree with the conclusion. It's not "logic" as I apply it as a logician, philosopher, or software developer. Lawyers (people on my side ideologically) will insist on the soundness of reasoning for decisions that they don't like but accept as valid.
So I don't find quoting the Constitution to be of any utility. None of those words what you think they mean. And fixing that requires basically throwing out the entire system of American jurisprudence. Which would be fine with me, to be honest.
