Regarding the Male\Stars hate, it's actually kinda goes deep.
So, Vtubing. Think of it as the lovechild of Japanese idol culture and anime. Now, both of these have historically catered to lonely guys. Everywhere these things go, it’s the lonely dudes they’re trying to appeal to. And because liking idols or anime wasn’t exactly mainstream, the fans ended up being kind of ostracized, and pushed into their own little corners of society.
Now, some of these folks, they don’t have any stable relationships outside of what they consume. Then 2020 hits, and we’re all locked down, making things even worse. Add in the Tumblr crowd from the 2010s who suddenly got into anime, and you’ve got quite the mess.
Vtubers, they roll up all the aspects of anime into one neat package. These talents are essentially role-playing as anime stereotypes, encouraging waifu culture, simping, and, let’s be honest, spending way too much money.
When you throw a guy into this mix, it breaks the illusion for some people. It’s like, "Wait a minute, reality check!" For others, it’s about keeping that pure, untouched vibe of Cute Girls Doing Cute Things, like in K-On. They don’t want guys messing up their fantasy world.
All around nasty work based on mental illness.
