Here's the thing about arguing with people. What we're really trying to do, when we engage in argument, is to manipulate others. We're treating people as objects - as hunks of clay that can be shaped and molded by our eager fingers. And what is the desired result of all this manipulation? It's to make other people into carbon copies of ourselves. We want to make them our clones.
There is something sociopathic about this. Sociopaths, after all, are known for their tendency to treat other human beings as objects. And many of them are also known for their ability to manipulate and control others.
Just stating the facts as we see them and letting other people draw their own conclusions is one thing. But sustained argument almost always entails more than this. It involves bludgeoning the other person over the head with one "logical" argument after the next - and often, such arguments are only superficially logical, mere verbalistic stratagems. Look at the way lawyers manipulate juries, or the way politicians juggle statistics and "studies" to prove anything they like.
There is something ugly and dangerous about argument. We shouldn't want other people to be our clones. The way to respect people is not to turn them into copies of ourselves, but to go our own way and let them go theirs.
