> Talk is cheap and political discussion is especially cheap. How do you propose to lead constructive discussions around these matters
I don't know about 'actionable items', but political conversation isn't any different than other conversations -- civility, the assumption of good faith, and an open mind are more common factors as to whether a discussion is good or bad versus topic.
The problem with political discussion isn't that it's political, it's that America (and possibly elsewhere that I can't speak to) has decided that "my side is good, the other side is bad". This leads to conversations that assume bad faith, and are close-minded, which makes those discussions "bad". You can't fix that with a set of rules, but you can enforce the same rules around those discussions -- people being rude, snarky or dismissive would be subject to censure, while people who are being courteous, informative and civil would not.
In short, I maintain that the problem with political discussions versus other discussions is that we treat them as different than other discussions. At their best, they can be a productive means of informing others to facts they may not have been aware, or elevating one's opinion from a basic understanding to a more nuanced understanding. But the more special we treat politics, the more the regular rules suffer, and blanket policies banning politics foster this special status in which vitriol becomes normalized, regimented and de rigueur.
So long as incivility is normal, the greater our partisan divides will grow.
