Yeah I guess I don’t. Why don’t you explain it to me? You seem to be quite a smart guy who picks up on everything. Please tell me more about how you are right and I am wrong.

Sure. So far you've claimed that (1) the smile at the end of rfonseca's comment should be viewed as good-natured and not mocking. This is not true of such expressions in general, but you've also claimed that (2) you have special knowledge, external to the thread, indicating that (1) is true.
You haven't bothered to support either claim, except to the extent that (2) supports (1); (1) is far from certain and (2) seems extremely unlikely, so unlikely that I surmise you didn't realize what you were saying.
This is not a universal convention.
