Wow! Long time no see! It's good to know you're still around
While I don't mind people using such displays of extreme pervyness and objectification of women as arguments, I prefer to focus on something else...
How does Nami reacts to all of this? One thing I said when defending LuNa before is how Luffy's quirks don't stop Nami from bonding with him
Instead of describing how flawed a character is, we could explain how those flaws impact the relationships in question. E.g. one of the latest chapter had Nami stating Sanji is not very reliable, words backed up by her own actions
Who does Nami choose to rely on the most despite his quirks or flaws? If we base our premise in the manga, and the author's works, we know it's Luffy
But, to support that conclusion we would need to put things into perspective by factoring how Nami reacts to each character, as well as who does she end up trusting the most, and who does she feel more attached to
The intensity and style of the emotional attachment are a reflection of how people may behave when their bond grows stronger
