Power scaling is the manga equivalent of junk TV, to put it simple. Not all of it, of course; there's that side of relaxed, healthy debate that sure can be fun. However, more than usually many users don't even enjoy power scaling and match ups but seem to act like hooligans of teams that happen to revolve around strength levels.
Someone should actually study what the hell is going on inside the heads of many Zoro and Sanji fans that are in the verge of sectarianism. It is toxic as hell how many of these power scaling discussions aren't even such but excuses for rotten people to behave like bullies if not something worse (the transphobic comments against Sanji which I've come across here are simply disgusting). We all know users who will address anyone as retard, delusional, etc. all with laughs, condescension and no respect the moment they face the smallest hint of disagreement on their opinion; the same individuals who keep turning this forum into pure toxicity because they won't limit themselves to power-level threads that don't even deserve their unfounded entitlement to begin with so their shit will reach all of us, including those who can have a polite debate on power scaling. And that's the problem here.
And again, trying to make exact calculations and mathematic estimations out of a manga made by a guy that clearly can't handle proportions and had Zoro, Brook and Usopp put in a cage by fodder fishmen is absurd and a waste of time, if not directly stupid. If they are going to debate over literally nothing, at least make it with education and intellectual honesty by first addressing that they're probably discussing pure nothingness that doesn't entitle them to be such morons poisoning the whole forum with bullshit.
