In matters of constitutional interpretation, it doesn't matter what I believe. What matters is what was understood and intended by the people who wrote and ratified the Constitution and it's Amendments. That's the whole point of "origianal intent".
If I believe something that is different than what they intended or did not address at all, then I have at my disposal the process of amendment to change the Constitution and rectify that. Once that's done, that Amendment then needs to be interpreted according to what I, and the people who wrote and ratified it intended.

And then of course there is the Bill of Rights:
"The whole of that Bill [of Rights] is a declaration of the right of the people at large or considered as individuals...[I]t establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." -- Albert Gallatin, letter to Alexander Addison, October 7, 1789
