“It is assur to believe LH you hear about somebody when it is not l’Toieles.”
I think this statement may be misleading. You are never allowed to believe Loshon Hora even when all the conditions of toeles are fulfilled. You are merely allowed to listen to it and to act on it as needed but without actually believing it. (Sefer Chofetz Chaim, Hilchos Loshon Hora, Klal 6, Seif 2)
I know you that you know that Yekke, but I just wanted to make sure that people reading this don’t mistakenly think that it is permitted to believe loshon hora when the conditions of toeles are fulfilled.
