I would like to point out that most Zoro fans / Sanji haters are not even talking about the Sanji fainting thing. At least i'm not and i'm not seeing any of the big names of the Zoro fanclub making fun of it.
I think most of us think it's completely fine and expected, to be honest the thing that would be crazy / not make sense was Sanji taking care of both King and Queen with no struggle at all.
I'm just pointing this out because the Zoro fans / Sanji haters have a bad rep and people say we make fun of Sanji for everything, but in this chapter funny enough, something that should've been shitted on by those people, it's not even being talked about that much.
In fact most of the talk about it IS by the Sanji fans themselves.
and most of the Zoro fans talk in this thread was about Zoro fighting King, we were fighting among ourselves.
