There is an expectation in polite American society that political matters are not to be mixed with religion, dinner, fun among friends, an etiquette. Politics is dirty business but supposedly necessary, so there may be pandering, campaigning, fact bending, but that type of gamesmanship is thought to live in its own realm. We practice the façade of stuffing political feelings in a box to keep from poisoning other aspects of our lives. Agree to disagree. It’s just politics, as they say.
