I was thinking about the "FUNNIEST VTUBER CLIP -> Sex" post (that OP deleted and that I hope it wasn't due to harassment) and I think a sizeable amount of people that dislike Vtubers don't actually dislike Vtubers, they dislike Vtuber fans.
Now, quick preface: I used to watch Vtubers, I don't anymore, but I don't dislike them or shit on them, I just moved onto other things, plus I don't like certain aspects of it as a culture on the corporate side. One of the biggest things I dislike, though, are the fans. I sincerely have never before wanted to not be perceived as something as much as I have with being a fan of Vtubers, not because Vtubers are cringe, but because being associated with Vtuber fans would legit lead to an ego death for me.
I obviously mean the ones that are the most infamous with that statement, if it wasn't obvious enough: The ones that seem to try and grasp at every chance to aggrandize, or, say, idolize Vtubers. You know the ones I'm talking about, the people that say "wow, normies fucking suck, they see Markiplier making weird noises and lose their shit, I don't get it" and 5 minutes later are laughing their lungs out at Amelia Watson making weird noises, the ones that'll see the Vtubers do something in a game and claims she's a Goddess Of The Game, The Best Player Alive At It, the ones that'll endlessly circulate clips of the Vtubers "using their real voice by accident" or "FUNNIEST VTUBER CLIP" (she said something sexual or burped) or "[Vtuber] is a FREAK?" (she said 'feet' or 'vore' or otherwise mentioned any other widespread milquetoast fetish), the ones that'll absolutely die on the hill of going to bat for the Vtuber or Vtuber corp they like (especially Hololive, Hololive shills are lab-grown weirdos with burnt out brains that you'd think are constantly in MK Ultra activation mode except just to defend Hololive at any cost and by any means).
This isn't every Vtuber fan, obviously, but this is what is known as the Vtuber Fan. This is what a lot of people think of when they think of "Vtuber Fans". And seriously, I find it hard to blame the talent -- in the majority of cases, because there's plenty of Vtubers that really lean on the so called "GFE", or "Girlfriend Experience", or "Really Fucking Vile Parasocial Shit", these ones can legit go explode and I support not giving them a platform -- because, see, streams are hours long endeavors for most streamers, and Vtubers definitely are expected to stream at least some good amount of hours per session. The majority of cases, these Vtubers are just making some jokes or commentary that may make reference to sex or involve more raunchy topics, which is completely normal for the average streamer, even non-Vtubers, but then Clippers (or Clip Channels), as they are known, clip only those parts, so for outsiders, Catgirl McTuber is known exclusively for making references to feet, piss, and saying the word sex a couple of times per clip, when the reality of the matter is, Catgirl McTuber only brings those up maybe twice or thrice every couple of streams. There are definitely Vtubers that leverage this, mind you, the whole "ehehehe if I say nipple and feet and imply being into this one obscure fetish, I'll get a shitload of views on my clips, which translates to new followers" so, almost as if on schedule like old Moistcritikal videos, suddenly they will unleash "uhhh yeah chat that health potion I just drank, it's so red and colorful, it looks delicious... Delicious like feet! Like a giantess' feet!" followed by a silence where chat goes "HUH?????" and they know that's going to be their clip, but again, that's not all of them, and some are really misrepresented. In a way, it's largely Clippers' fault that Vtubing in general is so often seen almost necessarily as this Thing For Perverts: Yeah, those clips get traction, from both enjoyers and detractors, and with those delicious views rolling in that aggressively, of course they'll replicate the formula more and more.
This, in turn, feeds into the usual view of the Vtuber Fan: It's easy for anyone not interested, not even hateful of the culture/craft, just uninterested, to view it as "Oh, vtubers? Those super perverts that only ultrafreaks like? Hmm yeah not really, no, I don't watch any of them".
And, again, the need, the compulsion, to aggrandize: "WOAH Pink Vtuber just dropped a new song! It's THE BEST!" maybe it's not bad, really, but it's definitely mid at best, and seeing people really push it as this breakthrough of music so aggressively because they jack it to the Vtuber's model, well, it doesn't sit well with Actual Music Fans of the genre. "WOW Dog Vtuber is FERAL!" she's literally doing much of what Markiplier-type streamers did and do, but she's got a cute anime model and is Female, so fans will go rabid, and other people will eventually find this behavior annoying out of principle.
See, these things I mentioned... Do they warrant hatred? Not really. A streamer can release a track and it can be mid and that's fine. A streamer can make noises and say "unhinged" things and that's fine. Streaming is about doing something you enjoy as much as it is entertaining a crowd, in my opinion. Going about it the way you want to go about it is always the right answer. But then you have these incredibly aggressively parasocially invested fans that make the visible, perceptible bulk of what a Vtuber Fan is, and that's when public opinion, well, it goes to shit, because it's not longer just "a streamer with an anime rig just chilling and doing their thing", it becomes "a streamer with an anime rig doing anything at all and this army of people with usernames like lolifeet9000 proudly proclaiming they are, in fact, the funniest feralest greatest internet supersensation alive, even though all she said was 'armpit' this one time in a 7 hour stream".
Mind you, there's plenty of legitimate gripes to have with Vtubing -- to name a few, the obvious clip fishing is annoying and especially the parasocial angle being intentionally leveraged sits VERY badly with me -- but these things are not universal, not all Vtubers are doing these bad things. I think Vtubers get a lot of unwarranted hate because they have the worst most annoying fans possible, and I would rather people make the distinction more often, if they hate Vtubers or Vtuber Fans (tm), because I think it's not fair to the streamers and I think you hate the Fans, actually, for very good reasons.
