Discussion with gigahurt started here. He wrote (quoting me):
Disagreements can be resolved!
I see your motivation for writing this up as fundamentally a good one. Ideally, every conversation would end in mutual understanding and closure, if not full agreement.
At the same time, people tend to resent attempts at control, particularly around speech. I think part of living in a free and open society is not attempting to control the way people interact too much.
I hypothesize the best we can do is try and emulate what we see as the ideal behavior and shrug it off when other people don't meet our standards. I try to spend my energy on being a better conversation partner (not to say I accomplish this), instead of trying to make other people better at conversation. If you do the same, and your theory of what people want from a conversation partner accurately models the world, you will have no shortage of people to have engaging discussions with and test your ideas. You will be granted the clarity and closure you seek.
By 'what people want' I don't mean being only super agreeable or flattering. I mean interacting with tact, brevity, respect, receptivity to feedback, attention and other qualities people value. You need to appeal to the other person's interest. Some qualities essential to discussion, like disagreeing, will make certain folks back off, even if you do it in the kindest way possible, but I don't think that's something that can be changed by policy or any other external action. I think it's something they need to solve on their own.
Then I asked if he wanted to try to resolve one of our disagreements by discussion and he said yes. I proposed a topic related to what he'd written: what people want from a discussion partner and what sort of discussion partners are in shortage. I think our models of that are significantly different.
