I have a number of liberal friends. We seldom talk politics, because we value that friendship, but even with them I find myself being careful what I disclose in terms of such things as what firearms I own. I have had a number of liberal acquaintances whose politics are the most important thing in their lives, and with them discourse is simply impossible. Honest to God, I was talking with one of them about snow tires last year and he pipes up, "Not gonna need them when Trump gets through destroying the planet, are we?" We couldn't even talk about snow tires. That's something worse than politics, it's obsession.
Make new friends is my advice. And pray the Civil Cold War doesn't turn hot.
