If the majority of people _want_ to fight and is more willing to act in bad faith to hurt the opponent / win the argument rather than willing to correct their opinion by discovering facts, I don't think any technical solution could, nor should, try to correct that ("nor should", because it could quickly turn into some sort of oppression).
That being said, I commend you for looking for such solution, if only because masses' mood swings faster than technical solutions are implemented, and your features will be there when people are fed up with constant conflicts.
