Is it even possible to engage such a person in a "fair discussion," especially when it comes to politics and religion? Does an "extremely stubborn" person really seeking debate, or does he or she seek to hammer someone else into submission? And in seeking to engage such an "extremely stubborn" person in debate does the other person, himself or herself, actually seeking debate, or is he or she seeking the ego satisfaction of possibly out-arguing the "enemy."
I'm sorry if this sounds like America-bashing but political and religious discussion is not something we do well at all in our hyper-competitive, talkative, ego-driven, consumerist, consumption society. LISTENING is not something we do very well as a culture, I'm afraid. We pause only to catch our breath and wait for our turn to speak.
I wish we could move closer to the Platonic and Socratic ideal. You know what? There's a religious scholar called Karen Armstrong, who has fascinating ideas generally, but also speaks to this particular issue. So, I think Dr. Armstrong can explain the Platonic and Socratic ideal of conversation better than I can. So, why don't we let her. If you get a minute, you might check this out.
