Arguing with people FAIRLY

Volokh makes the good point that I made a few days ago regarding NoRightTurn's postings

I've seen lots of people, left, right, or elsewhere, make the same mistake: Just because they think their adversaries are wrong in one way (e.g., propose an unsound view of the Constitution), they feel free to just throw a barrage of epithets at them -- their arguments are criminal, frivolous, pro-terrorist, dishonest, corrupt, Nazi, or what have you. And then, when a third party defends the targets against the unfair criticisms, the critics seem upset. How can you defend these bad people? They're clearly wrong!

Well, that our adversaries are wrong doesn't justify our making wrong (and unfair) arguments ourselves.
