That is pretty laughable and the Constitution did not eliminate (or want to) incivility.

The Constitution does not seek to dictate either morals or manners. That is not the point.

But linking your future with specific others, certainly implies mutual respect. That the Founders had that may be demonstrated in many ways--as, for example, the last lines of the Declaration (Declaration Of Independence--With Study Guide)--as, for example, the unanimous (electoral college) election of George Washington;-- as, by analogy, Washington's Farewell warning against the rise of factions, or regional animosities (Farewell Address).
