I think that there are two issues with that. The first is that religious minorities live in a world in which they are constantly bombarded by the concepts and values of the dominant culture, and I think the desire to counter-balance this in school as well as at home is very reasonable. The second is that some religions strongly encourage members to have quite a high level of knowledge of their faith. If a Muslim child isn't getting that at school she may well have to spend a lot of her evenings and weekends in madrassa. Given that religious education can incorporate key skills, I think it makes sense for Jews to prefer schools where Ivrit and Biblical Hebrew are language options, just as French and Latin are in most schools. None of that prohibits teaching children about other religions, but it makes sense for a community to want to teach them most about their own culture and faith.

In terms of worship being broad, I find that problematic. The issue is that it's very difficult to come up with a form of worship which really is neutral. In most British schools the communal act of worship is just a watered down Christian act of worship with the words 'Trinity' and 'Jesus' removed. It's nothing like how Jews or Muslims or Hindus worship. I'm not convinced that many non-Muslim parents would be happy if the 'broad' worship involved kneeling and prostrating to say vague religion neutral prayers. If we did manage to get to something in which no faith dominated that is inoffensive to everyone I imagine is being a bit like the holidays play in Southpark. I also think that, on a deeper level, it's representative of a philosophy of how multi-faith societies work which I disagree with. It says 'we're all basically the same' and then tries to mush up our faiths together to make something bland and meaningless. I think it's better to be open and celebrate our differences and show that we don't have to be the same to be able to cooperate in a vibrant mutually beneficial society.
