Or so it would seem in this article over on LiveScience.com. The premise makes sense. I know I find myself heating up when I engage in political chitchat with friends and family. When I step back to ask myself why, I always feel like I've been slighted by the other person. I tend to overreact.
After reading the above article, objectively approach your own views on things like abortion, the growth of government or whatever else you feel strongly about. Maybe it will help you understand how the folks on the other side see you and your point of view during an argument.
Of course, they're still wrong, aren't they? <grin>
