When Lieji Matsumoto found out the animators had used the Star Of David as the symbol of Captian Harlock: Endless Oddyseys villians the whole project whas cancelled and instead of a TV series turned into an OAV.
With Matsumotos own statement:
"My blood was frozen when I found the Star of David symbol appeared. I believe you cannot debase any religion...I bear that in mind whenever I make stories. I cannot allow my characters to appear in any anime that tramples on my philosophy."
Granted. Araki isn't Matsumoto. But since Jojo is FABULOUS hardcore fighting wich doesn't even stop for breath to even consider taking itself seriously I doubt anything that takes away from that is a good thing in anyones book.
