Menachem: I’m not sure what you’re objecting to. I simply quoted the Chofetz Chaim verbatim. Are you disagreeing with the Chofetz Chaim?
I was very clear:
“I would be very careful to research when and with whom these halachos apply.”
Because many GREAT tzaddikim were punished in the past for speaking negatively about IDOLATERS.
We must be very careful in the proper way to apply these halachos, and to whom.
