Fellow DIS posters... This should not be any kind of religious discussion. Which is off limits here.
This is about how a school staff member was rude and demeaning and nosey, and crossed every line.
MrsDuck, above, just nailed it.
I wish everyone would leave their own religious thoughts (would they, or would they not, pray. Etc...) out of it.
Tink, any private school, other than a regular government (County/State) school district is not "the government" aka: State.
So the idea of separation of Church and State does not apply... Just like religious schools operated by religious organizations, such as Catholic, Baptist, etc...)
Anyhow.... The thing here is that if this is actually a Montessori School, I would imagine that the Montessori Organization would have policies against promoting any obviously religious ideologies or viewpoints/agendas.
OP: Just to throw this out there.... If this is Montessori poilicy, and this situation were to become a real problem with several parents, and the option begins to be pulling the kids out of that school... Then perhaps an effort to contact the upper levels of Montessori would be a possibility.
