“Apparently, it wasn’t his mistake, but rather, he was misquoted here.”
Are we talking about the same thing? I was referring to the example given by Iacisrmma and not to the OP.
“There’s no way to target correcting a mistake in an online shiur exclusively to those who listened to it, so as long as it’s done respectfully, I don’t see why a mistake can’t be pointed out, l’hagdil Torah.”
This wasn’t the type of mistake that was necessary to point out. Also, he already discussed it with the speaker and the speaker acknowledged the mistake. If the speaker felt that it was important to post his mistake in the Coffee Room, that should be his decision. He should certainly be asked first if he is okay with it.
But again, are we talking about the same thing? Are you talking about the OP or about Iacisrmma’s example?
