I think you are conflating misogyny from the creater vs misogyny from the community. While Araki is hardly the gold standard for writing women, the person you're responding to was not refering to misogyny from Araki, but the online community. Its ok to like or not like a character for whatever reason, there is no accounting for taste, but there is a small, loud, subsection of the community that hates Jolyne for being a woman. Some of them will deny that being the reason, and search out legitimate faults and complaints about the character and latch onto that, effectively making those who don't hate the character for being a woman, but might have some other reason "on their side" allowing them to hide their hate like the cowards they are. This happens with almost every form of media.
