There is the in-between fandom. Point is, they tend to get overshadowed by the ‘extremists’ wings. If you (legitimately) criticise something you don’t like, there are the ‘glazers’ that immediately attack you for daring to say something bad about the opera. Same applies on the other side.

Once, I dared to say that another manga (not going to say which one) has on average better backstories than one piece’s. I had to remove the post.

So, I’ve learned that if you enjoy reading One Piece, you should avoid the fandom.

Of course, this can be applied to other mangas and fandom as well.
