“brush up on what the Chofetz Chaim says one is permitted and even a mitzvah to say about a regular repetitive sinner who commits his sins publicly. ”
Love this. the diligence in this particular mitzvah of denigrating a sinner reminds me of the 17 year olds who are also extra diligent in their observance of the “ad d’lo yada” mitzvah.
How bout the rest of them?
I have very strong doubts that the “denigrating” is as boundary-less in it’s application as you wish it to be.
