Gatsuga.. I'm seeing your POV but I steel think it isn't that easy...
the "Mero Mero Merrow" isn't something dodgeable.. as it is imediate, unless you can gess and dodge as soon as he does the gest.. or you're light..
No it is only imediate when your are touched by this power. Even Luffy thougth it was a Noro noro beam (foxy power), HE HAD the time to realise it, and we know that he dodged Foxy power many times (without using gear second). He didn't dodge mero mero for comedy and discovery purpose => this power has no effect on him (and in the anime it wasn't a really fast beam). But he surely can dodge it. Even the VA had the time to cut his hand despite the fact that he was facing Hancock.
Strong willed persons, that are not completely ****** (like sanji), sure won't be all "he is so beaaaauuuttiffuuull" but they will be affected..
This is what I said. They would be affected, but not enough to not react.
And to measure is power with Luffy's:
She destroyed a px with on it... (Luffy needed (one of) the most destructive attack of his wide choice of attacks to destroy one)
She hit his face, we didn't see it destroyed :

Even if she does it doesn't mean that she is so strong. It's just that her kind of ability works very well against Pacifista. It's not math where A>B=C so A>C.
She isn't even with damage lines, and he is in this war..
She hasn't used Haoshoku, wich he has mastered, and is, by far, her most effective abbility (a bit of speculation)...
He hasn't used is snake... the arm nr 1 for the rest of the Kuja's!!
She...he...she...he ? What the hell ? For 1 minute I was guessing if you are comparing her with Luffy again.

For now she was attacked by fodder pirates (and no Smoker didn't attack her, she attacked him), I don't see her being damaged by these guys. If you look at all of the Shichibukais in this war, the only ones who get damaged are Moria and Kuma...because they were fighting against..Jimbei and Iva..not fodder.
So you shouldn't kudge a boock by whats written in the back cover (couse the cover is the most beautifull thing I've ever seen)
The fact is I think you guys are the ones who are judging her this way.
the question is can all of them dodge her titshits while charmed maybe except zoro and robin will be unaffected, but you have to be totally an idiot or as innocent as luffy. but just the smallest smallest wicked thought can turn you to stone, look at VC momonga.
Strong willed guys will fight her if they have to. It's true that (but not Luffy), they will always be affected somewhere in their heart and will be affected by her Mero Mero beam but they'll react accordingly. Momonga reacted despite what he felt, it's the proof that you can fight her despite some feelings if you are stubborn enough.
It's quite possible even for Zorro to be somewhat affected in his heart but this won't stop him unlike fodders or womanizer like Sanji, if he has to fight her, he will.
