Political discourse today is an embarrassment. What was once a debate about proper governance has degenerated into an emotional cussing match in which principles are all but forgotten. It’s become so emotionally charged that many people are simply giving up on politics altogether. The low turnout at the last UK general election and the popular disdain about the US election and its “bad or worse” choice of candidates bear this out.

Unfortunately, if we want to live lives based on rational values, we must engage in politics. If we don’t, we risk losing. . .
