You see, that's your imagination, it's what you think happened vs what actually happened. I can do the same with "Luffy splitting the sky thing too" but that's an imagination as well. So then what? My imagination vs your imagination? We just completely disregard the actual story?
What pisses me off, is that I have to explain this to you even though you know this already but you're still trying to dismiss it because your own delusion is sweeter than the truth.
When we first met Zoro he was starving because of the deal that he made with Helmeppo, then in Wano we see Zoro's father also starving and still having enough strength to stay conscious and fight. Even if Zoro was (and let's pretend for a second) hungry, it still wouldn't be enough to put him down, not even fucking close. Plus, we saw Zoro eating the poisonous food, Zoro had been eating it for awhile even before Luffy arrived to Wano, and we also saw that the poison had no impact on Zoro cuz his body is that strong, Oda specifically had Zoro and Luffy eating poisonous food just to show how tough they are.
It never did any damage to Kizaru, and you know it, you know it but you're still bringing it up.
Again, if you can explain the above with your imagination then I can explain this with my own, but it doesn't make right though!
