I agree with your general points, but I don't think that they apply here. Why do you say that Eliezer hurt this guy emotionally? He did amuse a witness, and it's possible that later she came and laughed at the guy, or something, but there's no evidence for that. On the contrary, the guy got a little confusion, technically won an argument (after having to clarify his position), and just maybe got something to think about.

The only really cheap shot is citing Aumann.
