The problem isn't the platform, it's getting a critical mass of users. Until everyone is using it, nobody is.
Note well that this may not work to persuade them. But you can at least have the conversation.
It is noble to try. I suspect that you will always fail, unless the other person is uncommonly reasonable. Those views of life are the result of having vastly different experiences and backgrounds, and aren't something that typically changes after reaching adulthood.
This is fair. You can't really have a good debate with anyone if you don't agree on first principles. It think that's part of the problem with the worlds polarization these days.
We have this fundamental disconnect between 'the greatest good for the most people' on one side and 'the greatest good for MY people' on the other. It's literally two different answer to the question of life having value. IE - "They all have the same value." vs "Some are more valuable than others."
When you have disagreements that fundamental you will never find common ground. The zero-sum view of the universe is fundamentally incompatible with the other view.
The only way to stop it from becoming a thought terminating cliche when it comes up (in it's many forms) is to explicitly call it out as what it is - A fundamental an insolvable disagreement that can only be met with some level of compromise.
I suppose it could be, but the lizard people tell me it's not.
And "I don't want to" often means "I don't want to make the effort, but I would like the outcome if I did."
They just don't think it through to the end when they say it. Or maybe they do, and this is just an easier way to say it?
Essentially if you dismiss someone's argument as false just because it may have had a fallacy within it, that reasoning is itself a fallacy.
Some fallacy-seeking people ironically ignore this and just dismiss anything when they have the "gotcha, you made a fallacy therefore everything you said can be concluded as false" moment.
The idea that a single fallacy in a complex chain of reasoning renders the entire chain invalid just makes sense to programmers, who spend most of their time thinking in a step-wise and linear fashion where each output is the input to something else. This sort of "programmer style" thinking has crept into some surprising parts of society these days.
In real life, things are often more nuanced.
In effect, you end up getting them to agree with some otherwise unthinkable positions, just one plateau at a time. There's only so much erosion that can take place before they fall back to their own lines of thought termination (like "all I care about is immigration", or whatever). So you end up with a kind of "anchor" that we can both agree on (ex: corporations are fucking us), which still has the hard edge of politics. At that point, all it takes is for the politics to do enough that the hard edges start to erode. But, there's no accounting for that. Just gotta assume the people who are doing wrong will keep proving it (as they historically have been unable to avoid, no matter how hard they try or how long they are successful at it prior).
As you say: life is complicated. I know people will roll their eyes at this answer as much as any other response I could give you. And I know that a political-focused answer isn't directly analogous to many other situations. But, my answer is as simple as I can think to make it. Just meet people where they're meeting you and don't worry about forcing a point.

To use an example from the article, if I were to say "Let people enjoy things", and you were to denounce that as a TTC without consideration of my true intent.
In that case you may inadvertently be the one that shuts down the debate prematurely, and I may have actually had a valid perspective.
Doctors of that era, especially those who weren't too keen on hygiene, probably did not have exceptionally great life-spans.
