It happens after every presidential election. The opposition will be the death of America, friendships are lost, society is doomed. Except it isn't.
In actuality, proclamations of doom by political activists and those they whip into a frenzy never come to pass, because at heart all Americans share common moral values such as fairness and harm. And that is also why some on both sides are so afraid of new ideas. At least if we can go by social psychologists doing interviews.
