You're not demonstrating any moral sophistication by suggesting that people reach out to downcast Trump voters in friendship. Their politics are explicitly about exacting revenge and making their enemies suffer. Don't be stupid, they hate you and don't want your friendship.
And him being gone isn't going to make them stop being obstacles to anything good. They are going to continue to try to make the lives of the poor and the marginalized worse. You being nice to them today isn't going to change their minds.
I'd actually go one further and suggest it's actually a moral failing to start in with the "let bygones be bygones" shit right now. That's not kindness, it's cowardice. If we're going to have a functioning society, then sociopathic behavior has to carry a social cost.
Your conflict aversion isn't more important than the lives and security of the people Trump's politics targeted for destruction
