>>37559272imagine you're watching a female violinist performing a piece on stage, and while doing it, her boyfriend is raw dogging her from behind. would you be disgusted by this and walk out? likely, that would be considered a reasonable response by most.
now imagine the same situation except this time, the boyfriend is just fondling and groping her body. walk out? a bit gross but maybe some will tolerate it for the good music.
same thing again, but now the boyfriend is just giving her a peck on the cheek. some people will still walk out.
again, but now the boyfriend is just having a chat and flirting with her. most will likely stay.
yet again, but no intimate or sexual thing, the boyfriend is just chatting with her, cracking jokes. completely innocent, hard to imagine anyone would walk out at this point.
people are on a scale and because of the heavily the otaku/anime audience skews towards the social outliers, there are way more people in the vtubing fanbase who are so sensitive to the implied intimacy that they just can't enjoy watching the cute anime girls anymore if a dude is around and having fun with her.
