Judge listed what is wrong with Sanji according to him while Luffy thought he was listing Sanji's good qualities but they are both obviously wrong now: Sanji's skin is an armor
But if one is wrong, does it mean all of them are?
Let's see.
1) He is not the failure of Germa, he is their biggest success;
2) his skin is an armor
3) his cooking is not menial, attack cuisine is a thing
6) his mentality is not soft, we saw this dozens of times in the manga (TB, EL, ...)
So Luffy and Judge were certainly wrong at least on 4 points. What about the other two?
4) No royal pride
5) he is swayed by pointless emotions
What if these two are wrong too?
Might this be a foreshadowing of an upcoming CoC reveal for Sanji and Sora's drug being the origin of Sanji's fire?
(Luffy doesn't even know his VC.
