re Redleg’s post: I was at someone’s house once when they started to discuss the incident referred to. I asked them them to stop as it’s L”H. They used the old “common knowledge excuse”.
I pointed out that even if it’s true that “common knowledge” is permitted in terms of hilchos L”H (which I’m not sure about), what about “V’ahavta l’raecha kamocha” to the person’s family? If you were his son, would you like it that others are talking about your father?
They conceded that I had a good point, and changed the topic.
