Aw, here is where the Creator (Trinity#1) is sadly neglected. "Civility" is the essential basis of "compassion", ethics, morality, love and, ironically POLITICS! It is what is intrinsically "...in the image and likeness...."
Jesus came later, (in history) because He had an infinite understanding of what #1 had created in humanity and #1 willed Him to go find it, make it possible to set it right again and take it further.
Read Aristotle. His treatise "Ethics" is, rather surprisingly, the prelude to his "Politics" describes how "civility" is the ethical progression of mutual dependency to community, and is encompassed in the very nature of "love": "Love/friendship is a mutual benevolence mutually known".
DONALD TRUMP AND THE RADICAL RIGHT DO NOT ACKNOWLEDGE WHAT IS FUNDAMENTAL to civilization in the big picture right down to you and I in the neighbourhood. 
CIVILITY is a creational value, redeemed  and elevated by our Christ.
Saving the community from a lack of civility IS civility
