Avi k, not yotzei.
the comments are full of sinas chinam. It is very nice to show how lashon hara is non existent as well, and you are basically that deri is a rasha; as that is the example I gave, and you say mitzva lifarsem.
In addition, the chafetz chaim has not since come back to life and changed his mind. Last I checked, he himself said that he is more afraid of lashon hara so to speak, than the mitzvah to be mifarsem, and wouldn’t take the chance.
This is conveniently left out every time someone attempts to justify the addiction for lashon hara.
Even if most of the time it would be a mitzvah lifarsem, on the tzad of it not being a mitzvah, when it is not a mitzvah at all, it is an aveira, and there is no heter to me marbitz that aveirah lirabim.
