Much of that is due to incentives and not an inescapable aspect of public fora. Two notable examples that stand out in my mind of "people I probably disagree with about some things but trust highly" are HN's very own gwern, for exhaustive research, and Scott Alexander of Slate Star Codex. Somehow they have hacked, avoided, or self-disciplined their way into good-faith engagement without giving up ground to do so.

Integrated fact-checking would go a long way in political debates; gwern provides his own and S. Alexander, while less exhaustive, is relentless in analyzing his own biases and hewing to rhetorical charity. They would be less remarkable in a world where political debates had integrated fact-checking, as politicians would have to adapt.
