To be fair to Matto and Ladislaus, I just don't think they thought beyond the OP.
Matto was not speaking to this specific incident but was just citing a general definition of detraction, which Last Trad construed as an attack ... which it was not. I was simply chiming in ... in Matt's defense ... with regard to the technical definition of detraction, that it didn't apply here ... with any regard whatsoever to whether the accusations were true or false. Things can be false without being detraction. They could be slander or calumny, etc. or some other category or falsehood.
And I wouldn't have cared except for the fact that Last Trad went after Matto about it as if it were a personal attack, "Et tu, Brute?"
You can protest that we're arguing technicalities, but it was YOU who misconstrued Matto's clarification as a personal attack, and that's when I decided to chime in, since you had it wrong there.
