Sanji didn't overpower anyone and even if he did that doesn't mean anything in this argument.
Sanji kicking S jinbe while he was on nami and sanji kicked him away.
The argument is about sanji and the lunarian defense which he clearly didn't damage it.
I am not going to argue about IJ because i have no clue what this mode is capable of against that kind of po but this scene doesn't help sanji at all.
