What is the actual amount of indoctrination she’d get?
My atheist friends send their daughters to the same religious school the local parent(s) in each of those pairs attended, the same one my nephews attend. Two of them are teachers at the school (kindergarten and history). The school has a list of “RCC core values” which boils down to “respect, sharing, helping others”. There is a mandatory religious function once a year; other religious functions are “function or study/yard time” (chosen by the parents at the beginning of the year); in several courses there is an optional Religion class, with other courses being offered simultaneously (so, it’s not “Religion or study time” but “choice among several subjects”). One of those years is Comparative Religion; they offer the other options but those tend to be almost deserted, as the majority chooses to take CR. That one function was left as mandatory because it celebrates the saint after whom the school is named, there is a lot of singing by the different class groups, and polling of non-RCC parents interested in the school showed they’d rather their kids take part; if they ever want the kids not to take part, it’ll get changed.
