But did you learn about them and their history though? Even in one of the most laïc country in the world we heard a lot about various religions in relation to history etc.

Where I live now a lot of school are either super-liberal or the ones with a bit more structure are usually under this strange system where the schools are technically Christian but there's nothing about it in the lessons and kids from all religious backgrounds attend but they'll maybe have a bible somewhere or whatever because a lot of the funding for the schools come from the churches. That's even the case in some of these super liberal schools. Can't say I'm a fan of that and it's a part of why we're considering leaving.
