>>47603869>>47603920The point is mainly that people can find chuubas through various means, doujins just being one of them.
See : Fate series. Hundreds of thousands of people would have gotten exposed to the doujins first before ever touching the main series.
The "association" doesn't hurt the involved characters in any way, people are aware that it's a doujin made for lewds.
Same here, people are aware that it's just "AI Horsefucking audio" made for memeing.
Mori doesn't have any open horse fetish or anything, she rarely even makes such references (other than her sheriff roleplay).
The meme doesn't necessarily "define" her, as much as Mori antis would like it to.
