No argument delivered in debate is aimed to convince the opponent. Even if he is, he is less likely to be convinced than to retreat to different ground. I am reminded by Dr.Eck’s debate with Dr. Luther. Luther was only convinced that he had not gone far enough, that the common ground he thought he shared with the Church, was not there. Sometimes it serves a purpose to make the other side run up its real standard. Differences do matter. It was the delusion of the liberal priests back in the ‘60s that they don’t. Failing to see the importance of differences, they abandoned their callings and joined the enemy.
Then perhaps I can also remind you that when you refer to another FReeper by name in your post, it's FR courtesy to ping that poster.
