It's a tricky one. To what extent do you (do I, do we) accept other viewpoints, other ideas, aim for compromise and synthesis? And sometimes also thereby reconciliation? The times when you manage to say: "I'm sorry, I am or was being an asshole, I was wrong." Or at least: "I can understand your perspective too. Maybe we can find a way to connect." I think something like that is almost always the best result.
But what do you do when you feel that the other person's viewpoint (or even actions) are so far out that 'compromise' doesn't seem possible? If someone insists that the Earth truly is flat? Do you aim for a compromise where you agree the Earth is not flat but it's not a sphere (well, oblate spheroid) either, and the compromise solution is that it's curved like a half-pipe? Not really. But you can maybe agree to differ and still respect the flat-earther as a basically decent guy. It's fairly harmless. But if he then campaigns to have Flatearthism made a compulsory school subject?
Or to take it up a notch: someone (a man) who insists that women are worthless, that rape is good clean fun, and that 11-year-old girls should be forced to marry adult men. Can we, should we, still show acceptance here? Or even compromise?
There is still the principle of "Proscribe the deed, respect the perpetrator" (It's better in German:
Ächte die Tat, achte den Täter). It's a good one, but I find it challenging, and when certain lines are crossed, I can't do it, or only hardly. Maybe I need to develop further.
The Internet, and then above all social media, is a huge pressure cooker, or amplifier, or catalyst, for increasingly extreme viewpoints and discourses. Before, essentially baseless or taboo ideas, opinions, beliefs etc. would mostly remain niche or would require some kind of reality connection in order to gain traction. Now, as we all know, they become widespread and 'accepted' or 'acceptable' much more easily and quickly. Along with codes of conduct. It seems that nowadays it's quite a 'normal' move to make specifically addressed death threats - on the internet, anonymously - against a great spectrum of people who you don't like for some reason. Even if you'd never heard of them yesterday. Of course the extremer right wingers do this, and the religious fanatics and the chauvinists and mouth breathers, but also enough people from the extremer left wing, from some 'woke' quarters as well. It's modern culture. I don't think that people in general really used to be nicer back in the day. Or nastier. It's just that the new resonance spaces serve to ratchet everything up by orders of magnitude. And that changes the way people respond and bounce off each other. And it worries me too sometimes, how this will continue to develop.
So I guess I need to start by looking at my own behaviour again. Although I don't have the answers to the questions I ask above.
