Hard to believe, but it’s still over a year until the election we’re all obsessing about. That’s more than enough time for all the current front runners to fade away, and for new ones to emerge from nowhere. Meanwhile, we’re filling Facebook, Twitter, and, yes, blogs, with not so much political opinion as ad hominem. Never have slings and arrows so thoroughly disdained outrageous defeat. Have at them now, lads, if they disappear, you’ll have missed your chance to smite those who disagree with your clan. Come to think of it, disagreement isn’t even necessary, just designation as the Enemy.

The worst part of all this is the ugly deterioration of discourse in social media. Of course, the bar was never set very high to begin with, but now it’s steadily approaching negative numbers. More like limbo than the high jump. How low can you go?

There’s an insidious dynamic at work, one which, I admit, has affected me at times as well. You make some statement, simplistic because, in the buzz of the moment, you don’t feel like putting in all the nuance, all the exceptions and caveats. Besides, what sells on social media is the punchy one-liner. In any case, you assume your friends will get all that, because they know you so well.

But then, it turns out they don’t. Someone responds with an objection, which itself ignores nuance, the better to firmly repudiate the shallowness of your post. In other words, by this point, the two of you have posted opinions that, although you generally find the gist agreeable, you do not wholly buy into. It could stop right there, and often does. All it takes is one side or the other opting out.

But sometimes, you just can’t seem to leave it alone. You feel wounded; it’s a kind of betrayal for a friend to think you would actually believe such simplicity. How could they, especially since their response is just as trivial? Besides, you’ve thought of a zinger that will stop the whole process by making it clear you have the superior position.

You’re off and running. The “debate” slides further and further into sheer defensiveness, until each of you finds yourself fiercely defending a position you would never have even acknowledged before things got out of hand. Worse, a friendship is threatened over what usually amounts to a difference in nuance.

With any luck, something truly horrific hits the news just then, and the two of you can come together on what dangerous lunatics the other side are.
