Yes but you see, you asked to give a reasonable chance to those threads for example and keep an open mind about it.
The problem with thathough is that when one does that, if you try to give them a chance and take the time to post your opinion in a balanced manner, you are welcomed with all the meme quote posts, being called salty and a hater.
So when that happens, those making said threads and supporting them expose themselves as not interested in discussing those topics. The threads are just meant to be inflamatory tools, where you just troll and spam nonsense in response to anyone not joining the mindless wank.
It becomes more problematic with Zoro's fanbase simply because of the numbers. Like i can think of a couple of Sanji fans who goes to similar extents, but for each of those there are a multitude of time more Zoro fans who pollute the forum with the same shit.
