My advice for folks in this situation is to step back and let people process "everything".
Healing will require 2-4 years of disengagement and very focused and very respectful communication. If someone has "shit mouth", you step away and walk away and don't engage.
The only folks that can heal differences are ones within their political identity.
Also make note of those folks that are divisive which are the mocking "jays" of each group that poke fun and meme. Every 1 communication that makes people laugh, adds time to the timeout period.
The thing people don't realize is our economy and society can't handle another hit.
The safest thing actually for our country is a split house, because if the sweep happens in senate, then God help us.
There will be a fight.
