I agree that it's a lot harder to lose your cool or offend someone.
But it's also much harder to argue about truths. People in my circles say things like "I did a lot of research and this new mRNA vaccine is dangerous."
And there's absolutely no way to disagree with that, because they can't present the research and you can't read for yourself what it was. You can't critique the author/organization, you can't dispute any "facts" in the article, etc.
I think in-person can be good for very high level arguments, like "I believe in personal responsibility," and figuring out "I like this person even though I disagree with them." And terrible for intricate arguments like "gun restrictions will save lives," covid policy, etc etc.
I would like to see a shift back to previous times, where nobody was outing their political beliefs, and everyone didn't pretend to be an expert on domestic policies, covid, foreign policy, minimum wage, inflation, and everything else that they feel inclined to chime in about.
My grandmother (RIP) said in her youth (1930s), they didn't know how their neighbor voted, how their teachers voted, and they might not even know how their spouse voted. I like that.
