I was saying that you help Them, not the reverse. And if they're completely unclear, but I think they've put some effort into making some statement that just isn't coming across, I just ask. Something like "could you clarify? I don't see what you mean by somethingsomething in light of othersomething." Granted, I don't win many online debates that way, but really all I'm trying to do is get the person to consider some other way of looking at the picture.
Maybe you are being willfully ignorant, or maybe you live in such a monoculture, different ideas are like a foreign language you can;t deal with or understand?
