Certainly I get something out of it.Depends on which anonymous foreigner you are talking about. If someone shrieks nonsense to me on an internet message board, then I see no difference, no. The question is, do you get anything out of the conversation - ever? If never, then there's really no point in continuing a dialogue with the person.
I believe in dialogue and listening to the other side. Sometimes the opposing side in a debate will make a good point.
But more importantly I listen because it’s important to know how hateful and bitter and stupid the other side is becoming. I don’t want to ever be surprised by that.
