Hops - I'd like to hang on to that hope, as well.
I find that what you are describing is only possible if the other person has a minimum number of miles and personal experience behind them. It is truly a joy, then, to discuss politics... solve the problems of the world... and cooperatively dream up some solutions. Basic, raw values bubble up from those conversations -- held, believed, and actualized -- in common. It's like the old scene -- two young studs have a disagreement that escalates to a fight and when all the anger is worn out... they shake hands, throw an arm over the other's shoulder, go have a drink... and are the best of friends forever.
This vignette, I think... has at it's root the idea that people are valuable; all people. And that we can "move on" together.
I have been listening - albeit I usually don't subject myself to that kind of abuse of my beliefs. I've been finding that no one listens to me - in fact, to open my mouth and make the attempt at this kind of thing invites a form of interpersonal violence of the most childish and ugly sort. EVEN among people who profess to share the same beliefs. There is no other option for me -- except to walk away, retreat, withdraw -- shut up. It FEELS like this isn't even a genuine conversation; it feels more like a power struggle... which then poses a whole lot of questions... because it's clear that those seeking power are working very hard to disenfranchise "the other side"... in a tit for tat move... which really doesn't make a whole lotta sense, since there was no disenfranchisement that was forced on them... (cognitive dissonance has become more frequent for me lately...)
And this situation, has at it's root the idea that people are disposable - UNLESS they validate each other's beliefs. The tribal tendency, herd instinct, of buddying up with others of like-minds... is reinforced by those kinds of experiences. The confirmation bias at work in these "factions"... and their fact-checkers... is the elephant in the room. And Lord, don't try to talk about that either!! It's sure way to get verbally kicked, repeatedly... and cussed... and dismissed.
So much of this mess... is people taking "marketing" at face-value, having two sets of "facts" -- for each group -- with no facts shared in common (divergent views of reality, sometimes)... and to me, with my life experiences... well, I don't believe this is going to end well. It's too crazy-making. I want no part of it. Fortunately, it's not the first time I've wished I could just be beamed up somewhere else - LOL. I've got some practice with this.
