Three ways to "stay Christian" when discussing politics

I have friends whose political views run contrary to mine. This article by Jared Wilson is particularly instructive on how I should relate to them. In summary, the three ways are:

1. Turn some things off.
2. Remember your political opposites are sacred image-bearers of God.
3. Take your cues from Your Christ, not Your candidates.

I feel just the same way, and, at some point, have been guilty of this:

I cringe every time I see a friend or family member share some derogatory or dehumanizing comment or meme about politicians they don’t like. Sadly, objectifying our opponents has frequently been the way American [Philippine] political debate works, simply because it’s the way the world works. But Christians are not to act and look like the world. The stakes in our political rivalries may be high, but they are not so high that we must abandon the biblical truths that our real war is not waged against flesh and blood. They are not so high that we must deny the dignity of our political opponents, harping on their mistakes and flubs, scorning them with the hatred none of us owes to fellow human beings made in the image of God.
