How the world of the founders was a different society than the current. The rules of that society precluding much bad acting in public forums. In the higher society it would have been unimaginable that enmity from one president for another would take the form of public rudeness. I think that is why the various necessary requirements of transition were not written clearly into the constitution. Like most avoidable disasters it was a failure of imagination.
Fast forward to the present and we see the rudest piece of marginal DNA imaginable elected POTUS. Such a possibility was not on the founder's radar. Is that because we are evolved into a society over-stocked with people who have poor judgement when discerning the character of their fellows? Probably but it is a highly nuanced subject.
BTW, I don't condone beating children at all, ever. Hollering, nagging and threatening unfulfilled consequences, also, are all child abuse. Nor am I convinced of a great value to be found in condescension toward the "Country folk". Quite the contrary, we need their votes to stop the hordes of hate salesmen.
Skill in commanding one's "lizard brain" is the individual's only means of mastering unconditional self-control and should be practiced at every opportunity.
