You've probably gotten in a political argument in the recent past, whether with your nutso cousin at Thanksgiving or your militantly ignorant co-worker at a happyhour. And you'll probably get in another political argument sometime in the near future. Hard as it may be to believe, you can actually win these arguments.
One of life's most difficult emotional situations is the argument. Whether with someone you love, despise, or don't even know, conflict can increase anxiety and blood pressure, if not your sense of discomfort. Some people go to great lengths to avoid conflict of any kind, while others seem ready to argue at a moment's notice.
If you appear to be giving the other side’s position a thoughtful review, then the solution you propose will seem to be far more sensible. Furthermore, your opponent may come to your side without you having to do anything other than listening.
