Is it possible that Moscon might understand that what he did was wrong, but not
how wrong? Which - reasonable - might cause him to think the punishment was too severe.
Perhaps he understands that (verbally) abusing Reza was wrong, but not that he crossed a line when he went for Reza's skin colour in the argument. As far as he's concerned what he said might be similar to if he'd referred to the fact that Reza is French, or - if it was part of a Team vs. Team argument - the fact that Reza is on FDJ.
In fact, it's entirely possible that he has overheard/witnessed several other arguments that didn't cause the same reactions, and - honestly - doesn't understand why it was only what
he said that was punished.
He's not merely saying he didn't kill anyone. No one accused him of killing anyone, and that expression has a very clear implicit meaning: "Whatever I did, it wasn't a big deal and I shouldn't have been punished".
Does (Italian) Moscon know that implicit meaning?
He offers nothing in that interview in a way of an apology to either Reza or for his own actions but rather he feels no further responsibility for what happened.
He
already apologised to Reza; right when it happened! Or is he supposed to apologise to Reza every time he says something?
Besides, isn't it possible that the reason he's declining to say any more is because he feels like he's already said what needed to be said, and now it's Reza's turn to have
his side of the story heard?
