The reason people do that is because a lot of zoro's fanbase are arrogant assholes who bring him up everwhere they can, in topics he isnt even mentioned and circlejerk themselves to him. That is fine, but forcing your beliefs on others as well as poisoning every single thread in existence while wanking over his only feat, beating pica. Got irritating as fuck. So its no surprise people are bashing zoro rn, they dont hate the character. They are trolling a fringe group of his fanbase.
