Mdd: “They are brought down in the sefer “Chofetz Chaim.”
Please state where in sefer Chofetz Chaim does it say that there is a mitzvah of “Hocheach Tochiach Es Amisecha” with regard to someone else’s behavior that is not halachically defined as ‘assur’ al pi halacha?
“If somebody judges others wrongly, it is a ta’ana.”
A Taana? It is an “Issur Dioreisa”; as written in the Torah [and sefer chafetz chaim] “B’tzedek Tishpot Amisecha”. There is absolutely no difference between the obligation of Hocheach Tocheiach [if applicable] and the obligation of “B’tzedek Tishpot Amisecha”
