I’m afraid your mistaken the chofetz Chaim is referring to reshaim and kofrim FROM OTHER NATIONS other then yidden.
And this was the main reason why Yonah Hanavi ran away from Hashem when Hashem sent him on a mission to go to Nineveh and give over the dvar Hashem and bring them to Teshuva. And they were not Jewish. Cause Yonah was afraid it would be mekatraig on klal yisroel and Hashem would say look at the people of Nineveh doing serious Teshuva but my loving children klal yisroel won’t do serious Teshuva and Achdus together as one loving nation……. And Yonah Hanavi as every Jewish Navi loved Klal yisroel and would never be mekatraig on klal yisroel.
May we all wake up in today’s generation and face reality as we are in a time of serious horrific tragedies hitting klal yisroel and start doing serious Teshuva and Achdus together as one loving nation so Hashem can send Mashiach already bkarov.
