I've noticed that Marco Rubio sometimes makes statements on Twitter worth considering. Here are a couple relevant to the civility issue.
Trump haters still haven’t realized how much they help him with their condescension of those who either voted for him or don’t share their hatred of him. And how much they help him with their irrational hostility towards those who work for him.
Many Republicans won’t criticize Trump even when they don’t agree with him b/c it means siding with a media that nevers cuts him a break,turns even little things he does into an act of evil, are also unfair to them & in the end will still attack you anyway.
I don't agree that hostility toward those who work for him is irrational. After all they are facilitating a dangerous sociopath in the world's most powerful position. I support non-violent protest against them. We should look to people like Jesus, Martin Luther King and Mahatma Gandhi as examples of how to do this.
