Realistic!! Neutrals are realistic. If you are gonna be realistic, then you are not a fan. You don't have any expectations from Zoro, you just want to see the status quo. I want to stress that this is fine, but it means that you are not a 'fan'. You just like 'some' parts.
While we fans defend Zoro through thick and thin. Do you know who Oden fans are? The ones who defended him after the last chapter. Not the ones who was praising him beforehand.
That's the difference. When Zoro's portrayal will take a hit, you will just say 'this is Zoro's limit' but we will defend him and find reasonable (and some unreasonable) supports for him.
