Convent schools are the worst. I've faced hinduphobia entire my school life (no more staying quite). From morning assembly to the school leaving prayer everything was typically so Christian. Tilak, rudraksh or any other religious ornament was prohibited but not rosaries.

I've seen teachers insult Hindu practices n even festivals. Be surprised, even here the majority of kids are Hindus but nobody dissent when teachers or students make hinduphobic comments. The environment in convents makes sure to imbibe Christianity in you indirectly.

A student may not convert to Christianity but, certainly, may not remain a Hindu after schooling.

Not to forget those short class assemblies on how diwali is responsible for pollution and holi leads to water wastage, distribution of Bible, rosary n forcing children to take them home. Separate classes for students- catechism for Christians and moral science for the rest.
