isn't it better to just ignore them? I believe they are only troll.. Don't waste your time on people like that. If shanks laugh at people who bad mouthing pirates, if Luffy and Zoro didn't give a damn to people who laugh at them on the mock town, why can't we giggle over some childish fans who bad mouthing one piece. I feel a lot of pity over them, they have no sense of great manga, so just ignore them.
Now, we know that one Bleach reader is a superficial b****.
My fellow intelligent one piece reader, lets act as cool as Shanks acts before the mountain raider in vol 1.
