(Could someone point me to a tutorial for replying? I'd have edited down the quote, but I saw no obvious way to do it.) Back in the 90's, I was very active on the Usenet, and one of my time-wasters was arguing for Objectivism. After enough experience, I concluded that my motivation for doing so was not healthy. I had got it into my head that if I just said the right words, my opponents would "get it". Of course, they almost never did, and never if they were truly committed to their opposing view. This, I decided, was codependence, and I basically just walked away from such activity.
