Sophia's main bully is Angela, the goth. Goths are often criticized by Christian Moral Guardians (they're mainly accused of Satanism and listening to demonic music), so no wonder Angela has a low opinion of her.
Sophia manages to convert one of her classmates, Zoey, into being a Jehovah's Witness. Sophia also holds homophobic views and was told to accost another classmate of hers with two moms about why being gay is wrong. If her influence grows, the school may not be a safe place for queer students.
Sophia also managed to convert Zoey right under her parent's nose. For any parent, the idea that your child could be indoctrinated into a (potentially) harmful religion without your knowledge or consent, is a rather uncomfortable one.
One episode features a new girl joining Sophia's class, who is expressly a Hindu. Sophia, after seeing the other kids ostracize her for being different, offers her friendship and is shown striking up a conversation with her. It seems sweet at first, but then one remembers how often the kids are told in-universe to preach to their classmates and try to convert them... Furthermore, if it’s becoming clear that the girl can’t/won’t convert, Sophia will be pressured into no longer associating with her.
