Who gets to "impose morality"?

[Alexander the Pretty Good]

And the dead should never get a vote. To paraphrase Chesterton "Tradition is the means by which the dead majority prevent the rule by the oligarchy of those who merely walk the Earth."

When do the dead get a vote? In the Constitution? That's also absurd. To literally apply ithat line of thinking would require society as a whole to update its descisions every time there is a murder trial - because the past laws against murder could be made by someone already dead.
