Very few are capable of understanding the constitution. Even a lifetime of effort is some times insufficient. Where do you see these people capable of such sustained intellectual endeavors? Where were they ever?
For the first hundred years or so there were few misunderstandings about constitutional basics, except for 'states rights' & slavery. And non-intellectuals certainly understood those issues.
Why are they incapable of understanding anything else of such complexity? Being to read the words does not mean one can understand what they are saying. Like a great poem by Shakespeare there is a wealth of meaning in the simple words and phrases little of which is gleaned by an ordinary reader.
You see 'penumbras', perhaps? -- You protest-eth too much, imo.
Your agenda wants to find it complex, in order that it may be interpreted in your way of thinking..
Our constitution simply promotes individual freedoms. -- 'Laws' that infringe on these freedoms are repugnant to its principles.
In fact, I would wager that a good punishment for most of our fellow Americans would be to force them to read the constitution. They would claim to do so would be unConstitutional itself.
We require a constitutional test for natualization.. - I think the same type test should be required in order to vote..
