You know the people here are just a verrrrrrrrry small fraction of actual OP fans?
And even most who write around in forums (which is already a very small fraction of people who actually read it) do not care about the Sanji vs Zoro stuff, it´s just this forum has an extraordinary amount of them literally arguing every instance about their favorite characters and trying to bring everything back to them, and most of the time even if they argue something else, you know they are arguing from a stance of their character has to look good.
The freedom provided by the mods around here has positive and negative consequences, it would be disingenuous to criticize them for it when most of the time it actually has positive effects and people can discuss freely but yeah, Zoro stans started in this forum, basically spouting one nonsense post after another, and instead of saying who cares, Sanji fans tried to follow, and now you have two sides usually poisoning most discussions.
Like i said, small fraction, i do not know how it is supposed to influence OP at all, but it sure as hell influences their perception of OP, pretty monotonous affair if you constantly have to think about one character.
