No one hates women more then gay men.
It can't be because she's a woman, because there's tons and tons of woman vtubers, who don't solicit this kind of rage.
It also can't be because she's a woman with right-wing sympathies, because a bunch of those exist as well but the others don't solicit that kind of rage.
It also can't be because she's a woman who expresses what she wants in life even if it doesn't play into/enable the most bottom of the barrel degenerates, because a bunch of those exist as well, really big ones too like the orca and the demon girl, but those don't solicit that kind of rage.
There is obviously something about her specifically that stands out in a way that is unique.
Degenerates hate kirsche because they feel their fantasy world is being encroached upon by a (comparatively) sound-minded individual, and they will defend it tooth and nail because they have nowhere else to go.
If that were the issue, they wouldn't actively seek out her channel, watch through hours upon hours of her streams in search of one clip to repost 10 times on 10 different pages, or seek out her discord to run gay ops on it. They'd just stick to their /r/traaaans subreddits and their fag-only boards and websites. But in some cases, there is clearly more at play. It's like the thought of her existing and speaking unhindered fills some people (specifically trannies) with a deep existential fear.
That would be the Twilight Zone of all streams. It would be highly interesting.
The Jim/Josh crossover stream was a twilight zone stream too. Jersh even said it would only happen if Ethan Ralph was in a car chase with the police, but then it happened without such a chase to set it up.
But even if they have some clear overlapping struggles with how both have to face off with weaponized neetdom, it is not going to happen, the odds are like 0.000002%.
Jersh is still in his 'defending white women' / 'there is still some good in her' arc, tripping over himself to please and appease any wamen trolls here or on adjacent websites. Which means the beauty parlor holds absolute power over what he can or cannot say or endorse. He cannot endorse anything anime-related. No anime shows he might have watched, no vocaloid avatars like hatsune miku and absolutely no vtubers whatsoever. Whenever he does, it is met with immediate backlash.
