Rav Dovid was just living and you could have had your answers.
But that would assume that you are open to being taught something.
Instead you have the audacity to insinuate that Rav Dovid didn’t know what he was talking about. But still Rav Elyashiv was mislead by it. Anybody who knows how to learn anything at all, can see what a fool you are.
I give up trying to get any answers out of you. You are the toughest poster I ever interacted with on this site. Even worse than Health who I miss dearly.
