The documents aren’t the problem. It’s what we have allowed to happen to them, partially at the hands of the legislature, but mostly at the hands of SCOTUS. Its “penumbras” allow it to interpret and enforce its interpretation.
Don’t forget that SCOTUS was responsible for the Dred Scott decision…their politics change,but it’s always politics.
