There's something funny I noticed:
en.m.wikipedia.org
On this list, you can see that Oda is the third bestselling fiction author alive.
Number #2 is JKR who recently has caught quite the the negative media attention with transphobic statements.
The difference in sales is 30 million copies. That's not much and One Piece will continue for at least another 6 years. Oda will certainly beat her.
With a story that embraces what she loathes, and in a way that is certainly not political correct
The more I think of it, it might actually all be just because of it. The number #1, Danielle Steele is quite old already, which means JKR would have had a shot to be the number #1 herself... If it weren't for Oda and One Piece. Maybe she actually looked into the story that is going to beat her in sales, wouldn't be too farfetched, and that caused her to snap? Consider, both made the vast majority of their success with a single fiction universe...
In any case, this is soo hilarious.
