It is much harder to distinguish ignorance in current political discussions -- in part because nowadays political preferences often induce ignorance in those you'd think most capable to judge it in others.

As a result political discussions become largely unresolvable. People participate not to share information but to give witness to their particular beliefs, which inspires others to do exactly the same.

More technical conversations may grow for a while, as more interesting points and lines are opened, but after a while what there is to be said, has been said, and the conversation moves on.

With those dynamics, political conversations are likely to add noise around signal until they drown it out. Unless actively beaten back.

The real solution is to change the way people talk and think about politics. This seems unlikely.
