Can't blame them.
I would drop it too after last chapter.
N8ce new girl get raped right awsy, while the other annoying girl is protected everytime by plot armor.
No fucking kidding.
And it gets worse the more you think about it.
"Oh hey, Kaname very obviously got raped by Madoka, and the fucker didn't even try to cover his tracks - Maybe I should, ionno, call the police? Or at least tell her twin brother what happened? Nah, I'll just STFU and be super mysterious about it while I try to solve everything myself"
Inb4 twin bro starts thinking that Uruma's the rapist instead...
