Zoro fans are the worst, don't get me wrong there are some pretty bad Sanji fans as well but Zoro fans are still way worse. They can't take criticism, they get angry if you make fun of Zoro, and they will sometimes even insult you if you argue with them about Zoro. They treat Zoro like he's a god, and the most perfect character in the world.
Of course not all Zoro fans are bad, there are some good ones that just wants to wank off to Zoro and do their own thing.
Also if you're someone like this user above who can't even acknowledge that the Zoro fandom is toxic and are turning a blind eye then you are just as bad the toxic Zoro fans. That's like seeing someone commit a crime, and then pretending that you didn't see it.
