To be honest -I don’t know where this Rabbeynu Yona is, but it doesn’t really matter. Even if you are correct and he does say what he you say he says -this doesn’t change the Halacha.
The C.C. says that the listener has to know whom you are talking about to be considered L.H., not the way you misconstrue it.
All this R. Yona can do is make it a Mussar Deherr, not a Halacha!
So I’ll repeat it again, lest anyone starts believing your nonsense -in order for it to be L.H. or Rechilous you have to know who the individual or group is – that the guy is talking about!!!
