We all have our less enlightened moments. Better we not afford ourselves easy intellectual justifications for being our worst selves.
As the quip goes: the greatest evils are perpetrated by those most assured of their own righteousness.

When the politics of a nation shift so far in one direction we get into a situation where supporters of that shift don’t deserve respect. Stalinist Soviet Union is an extreme example of this.
And how do you feel about them feeling the same about you?
Mutual righteous hostility is why ethnic and religious wars simmer forever, because there's always a convenient justification for acting violently towards others (and them towards you).
I don’t do anything at this time. But I understand why there are those who do have vitriol for supporters of a rapist who lusts after his own daughter. There are times when a nation’s society fractures as the social cohesion evaporates. We are beginning to be in such a time in the U.S. Well, it appears that way to me. Only time will tell.
