It's cringe that Zoro fanboys are trying so hard to downplay Kaido because Luffy's keeping him at bay in base, but let's not act like Luffy fanboys aren't getting nightmares every time Zoro does something semi-impressive and do everything in their power downplay the guy.
To both the fandoms: If you do something bad to others, don't expect them to act reasonably when it's their turn to pay back.
