In my experience both tend to be wrong more often than not. Neither wants to listen to the other for the reasons above and then fail to benefit from the others experience.
I really enjoy talking about politics. I noticed, that I often can find common ground with almost everybody. I got used to be forced to search for common ground to have any conversation at all. This is because I disagree with most people I talk to on even the most basic stuff. It started when I was about age 17 or so. Mainly because I started reading stuff and thinking about it myself. Prior to this I had no opinion at all.
Also having changed my own opinion on major things helps me a lot. I haven't changed my principles by the way. I just noticed I was wrong about some "hot topics". So that actually helped me a lot to understand I might be wrong, and I think people feel this when I talk. I still have strong opinions. I simply understand I might be wrong and express this. And always try to understand better. Basicall, I feel like I know nothing, but then I notice I often understand more than a lot of people. Which I think is something quite easy to achieve by simply don't caring much about who is right or wrong and talking to everybody. Just assuming all people involved in conflicts are human and trying to understand even 'the bad actors' whoever I believe them to be.
Another funny thing is I often get along better with people from the opposite political spectrum. Because then it's clear we deeply disagree. So there is no point in trying to convincing each other. This makes talking about hot stuff a lot easier. People from the same political spectrum often care to much about small differences to have a meaningfull discussion.
Also through talking to family and friends I notice how much in general personality is mixed with political opinion. I think I can draw the lines because I see the paths they take in their live and the mistakes they repeat over and over again over time periods of many years. I don't think this is obvious enough to see with strangers. At least I wouldn't have without the close relationship. That also makes me humble. Sometimes I notice how my political opinions reflect my own personality, but I think this is hard to do on my own. That's another reason to talk to family and friends about politics.
I feel if one manages to destroy relations then one is doing something wrong. On the other hand, I also noticed some people are kinda sensitive and take things personally. Especially, when talking about some hot topics like ongoing hot or cold wars or alledged or real occupations. So I try to be carefull. Mainly by immediately feeling for boundaries. How far can I go? I mean it is quite easy to say "Ok, maybe I don't know/understad enough. What do you say to this?" Mostly, I am genuinly curious. Sometimes I just feel the duty to offer an honest conversation.
I doubt most folks who talk about politics really "want" to, as much as they feel a responsibility or need to do so out of compassion or even desperation. Nearly everyone would prefer if we all could just get along, but we don't get along, and pretending we do seems like a great way to just allow the majority to steamroll the minority.
The actually-oppressed stay in hiding. Whether they're gay in 1945 or Russian dissidents today, or political dissidents in today's western overculture, "eschewing discussion of political topics" is a mandatory survival strategy. I can relate because I am in this position - having to pretend I'm something I'm not on a daily basis in almost all contexts.
Someone who feels they can afford to speak politically on things others won't like must be in a pretty powerful position.
What do you think that person looks like to someone who knows they have to keep their mouth shut to not have their life ruined?
Having the right to even talk about your issues is an important and oft-overlooked privilege.
I hope you realize the comment you just wrote suggests that the oppressed should stay in hiding...
Again, I'm speaking about people (family/friends) that I know their background and I know that it is a huge waste of time trying to argue against their biased POV of "good old days of dictatorship". I'm talking about people that don't care about the oppressed.
But if you don’t already know the person’s views, it seems unwise to assume that “old person = supports the old regime,” since this will result in you missing opportunities to connect with potential allies.
Even as they metaphorically step on the throats of the people you care about?
But there's one space where no trained skill seems to work: politics.
I just avoid at all costs discussing politics with friends and family, because it simple leads to nowhere. Older people usually likes to stay in a position of power in those dicussions like "they know much more than us", so in the end I just stay quiet and "agree" because in the current state of things, people feel so much harmed by words that its better this way.
