They just hate anime and anime-looking things because daddy Josh hates it. There's nothing more to it.
If there is a perfect example anyone can look to regarding the cult of personality Null has over the site, this is it.
I've lost count as to how many times people have regurgitated the same "anime avitar = opinion shit/discarded" talking point against a user, even if that user is correct! That to me is the worst part... people will willingly brush away all logic, intelligence, and common sense all because someone with an anime avitar fucking DARED to voice their opinion, even if it contributed something to the conversation.
By brainwashing his users into thinking like this, Josh has effectively gotten the targets off of his back and onto something else, to the point where people will actively play defense for his neko shota fetish. "Oh that was a long time ago, people change!" yea, they do, but don't you think that it's even a little suspicious that someone that likes anime related things is just outright calling a fatwa on ALL anime-related things? And don't you think that it's even a little suspicious that he has recently given attention to the V-Tubers.... or even wanted to be like one even if it was some stupid animal? He hasn't changed one bit. This kind of behavior basically says that he is either ashamed of his fetish or is sick and tired of people making fun of him for it. Either way, his only recourse is to take away everyone else's toys because he got caught playing his, so everyone else must suffer. Either that, or only give O.K. to things that only HE approves and the zombies will just follow suit.
Or to put it in another way, his projection is so fucking massive, fucking IMAX would go out of business because takes up TWO baseball field sized parking lots for it.
