Oh yeah I forgot, the constitution has exceptions, like the fact that felons can't own guns, or that those in prison can't vote.
"The idea that institutions established for the use of the nation cannot be touched nor modified even to make them answer their end because of rights gratuitously supposed in those employed to manage them in trust for the public, may perhaps be a salutary provision against the abuses of a monarch but is most absurd against the nation itself. Yet our lawyers and priests generally inculcate this doctrine and suppose that preceding generations held the earth more freely than we do, had a right to impose laws on us unalterable by ourselves, and that we in like manner can make laws and impose burdens on future generations which they will have no right to alter; in fine, that the earth belongs to the dead and not the living."
--Thomas Jefferson to William Plumer, 1816. ME 15:46
"It may be said, that the succeeding generation exercising, in fact, the power of repeal, this leaves them as free as if the constitution or law had been expressly limited to nineteen years only. In the first place, this objection admits the right, in proposing an equivalent. But the power of repeal is not an equivalent. It might be, indeed, if every form of government were so perfectly contrived, that the will of the majority could always be obtained, fairly and without impediment. But this is true of no form. The people cannot assemble themselves; their representation is unequal and vicious. Various checks are opposed to every legislative proposition. Factions get possession of the public councils, bribery corrupts them, personal interests lead them astray from the general interests of their constituents; and other impediments arise, so as to prove to every practical man, that a law of limited duration is much more manageable than one which needs a repeal."
--Thomas Jefferson to James Madison, 1789. ME 7:459, Papers 15:396
"The generations of men may be considered as bodies or corporations. Each generation has the usufruct of the earth during the period of its continuance. When it ceases to exist, the usufruct passes on to the succeeding generation free and unencumbered and so on successively from one generation to another forever. We may consider each generation as a distinct nation, with a right, by the will of its majority, to bind themselves, but none to bind the succeeding generation, more than the inhabitants of another country."
--Thomas Jefferson to John Wayles Eppes, 1813. ME 13:270
