Do we? Most discussions in comment sections between people of different persuasions tend to be toxic and abusive these days. when moderators attempt to impose standards of civility there's a chorus of complaints about 'censorship'. There have to be limits to patience with bad-faith dialog, otherwise you're just enabling trolls and abusive people.
You and I probably have different political views and yet we are able to remain civil.
Everyone in my neighborhood, every single neighbor, speaks different languages, has different cultural origins and most are of different races. We don't support the same candidates or policy positions but we do all support and look out for each other.
I guess my point is, politeness even when there are significant disagreements is possible. We need to analyze the communications that do and don't work, find the similarities and patterns and encourage the beneficial ones while discouraging the negative ones.
