Mihawk is the only character in that lineup that has a sizeable amount of the fandom actively denying the reality of who the character is.
Even the biggest Sanji hater in the fandom isn't out here saying "lol, Sanji ain't that good of a cook!" but you have plenty of people trying to say the Worlds Strongest Swordsman is a fraud, below Vista, about to be killed by Shiyru, Buggy's lapdog, Paint merchant etc.
You have some guys openly talking about Zoro maybe already having beaten Mihawk in the time skip/long since having suprased him even though Zoro DIRECTLY says in the Manga he still doesn't think he is strong enough yet. They actively deny reality.
Like, maybe I am just blind but I haven't really seen any of the other hatedom characters being forced to deal with that sort of shit.
