Toxic? If I went back 6+ years or so, Naruto discussions were more toxic on average I'd say. Really all Naruto had going for it was powerscaling, OP had a lot more discussions in other areas aside from VS.
Now that the series has been over for a long time it's easy to say One Piece, especially when those Naruto fans have migrated over to One Piece.
Delusional? One Piece fans.
