Detatch your ego from One Piece, you're just a consumer, critique of one piece is not a critique of your existence.
A decade ago I spent hundreds of hours watching this thing, so I have a right to skim it for 5 minutes every couple weeks.
You can't police other people's reaction to the story.
I hope someday you find a forum that does nothing but praise One Piece, so you don't have to feel these negative emotions.
