A VTuber, or virtual YouTuber, is an online entertainer who uses a virtual avatar generated using computer graphics. Real-time motion capture software or technology are often—but not always—used to capture movement.
Is it? I'll admit I've bounced off the one Drizzt book I tried reading...twice. But there are some damn good novels in the Forgotten Realms line.
And even if they are reading low-grade schlock, is that not at least equal to (and frankly probably better than) watching lazy overly-sexualised live streams?
Yeah, there's low-grade schlock of anything if you look for (or single out) it
Plus we were mainly talking about identities, not the streams themselves. Though I do want to point out that the cartoon itself is using the eekum bookum girl ...so...if that's sexualized then...okay?
Honestly their impression seems super biased based on their perception of one streamer they liked. Vtubers - just like other streamers/content creators - range from "primarily doing porn" to "guy that has been streaming for 10 years decides to get a cute anime girl vtuber avatar for fun".
There's a tendency for roleplaying a character, but it's not a necessity and definitely not always sexualized and plenty of vtubers are just regular streamers with an anime avatar.
There's of course some weird simp culture in many audiences, but that's no different from other female streamers either. From what streamers have said it's hard to prevent unless you stop anything close to it from happening, and few people want to do that when it also just factually brings in a significant amount of revenue.
Most also don't mind or even like people drawing porn of their avatars, but that's more due to humans being horny by default rather than particularly exploiting that for money.
The easiest way to understand is a streamer (think Markiplier or Pewdiepie) but instead of seeing their face, they use an animated avatar that follows their movements.
Extra layer of anonymity and makes people less focused on their day-to-day looks.
