They deleted my response, but I will try to give a short response to some of your points:
“So claiming I don’t understand what you meant because I don’t know the context is the same as someone claiming you misunderstood their intention.”

And by the way, if Shimon would in fact tell me that he hadn’t expressed himself clearly and I had misunderstood him, I would believe him (as I would expect you to believe me in this case).
