>>18336326Because hololive lives rent free in heads of some more degenerate Nijifans, while Hololive community doesn't really care that much about Nijisanji. I have honestly no idea why that's the case, as I'm only here for a year and a half and even then you had coincidences like a lot of people harassing Aloe also having Niji oshis.
However those antis are just a vocal minority, most of Niji fans I know are chill people. Kinda wish those two fandoms had a more friendly relationship, but people will be people and the tribalistic urge of doing unga bunga on the another camp gives a meaning to lives of many, especially on venting corners like this board.
