JO must be understood in the context of the community she has surrounded herself with. Despite her repudiation of her TGWTG past, most of her fans discovered her from that site. Most of them were probably sexually attracted to her, but were unable to express it given her frequent shows of disgust and self-pitying regarding anyone lusting for her. She would give vocal condemnation for even minor actions like someone asking for feet pics on anonymous ask.fm, obviously encouraging any trolls to send more of these messages- she framed this as a 'being a woman on the internet' problem, when it is really more a 'predictably spergs out over the slightest provocation' issue. These fans were never able to voice their sexuality, and instead went into subservient mode, protecting her from all criticism.
One revealing detail of JO's Franxx rant is the way she immediately tries to associate the show with the Alt-Right. This might strike the reader as alarmist, intended to raise the stakes and allow her to paint those who object as Nazis (which she did), and the reader would be right. But this is the typical tone raised in the ANN community- all are 'quirky' nerds who just want to have fun, but completely lose face and resort to attacks of Nazism when disagreed with. If you object to their progressive politics, you are no longer human to them.
A few years ago a large amount of the male members of the community suddenly turned trans (this was shortly before JO did). I am honestly unsure whether this is due to both anime and transexuality being heavily associated with :autism:, or some hive-minded groupthink. JO and the ANN band view masculinity as innately entitled- they talk about how men tend to view themselves as the main characters of their life, thinking of themselves before others, which contradicts the SJW ideal of spending your entire life thinking of what your neighbor thinks of what you say, a world of people thinking of nothing but what others think of them. A man enveloped within an environment where his masculinity is seen as a character flaw should be immediately questioned when he decides he's a girl.
JO, like most FtM transexuals, is pretty woke, and constantly tries to undercut her 'masculinity' so as to not risk intimidating any women, making herself into a twinky girlyboy in the process. It's a monkey's paw wish- you can find a community who will encourage you to become male, but they will turn on you if you express any masculinity which they find intimidating.
Anime is a problematic medium made by a sexually aggressive nation- even in 'pure' anime, there is always tightly suppressed sexuality just under the surface. This, in addition to the animation itself, is what makes it interesting. JO's band can only support anime's skeeviness in tightly controlled ways, when they can frame it as an expression of positive sexuality (usually homosexual.) But gender roles are a part of sexuality as well, so their appreciation of anime will always be limited by their lack of acceptance of perversion. They treat anime's problematic nature as a reflection of how ingrained their cultural enemies are, but the fact that they have to intentionally impose their SJW worldviews on artists shows why they will never win- we are led by our sexualities and souls, and no amount of finger wagging will change this.
