Practicing Islam should be against the law. :)Easy Does It:)
I don't know how you can say it is a culture. You may think it is a false religion, a bad religion, etc.. But a culture? How? It has different sects, interpretations, holy men It has a god and prayers and holy books.
The standard in this case, in my opinion, is that the children are being required to say prayers to a god.
I would have no objections if they were asked to eat pita bread and falafels, wear robes and do belly dances. That is "culture". Even, perhaps, giving them rugs and showing them how to bow 'might' be construed as cultural if they were silent and not required to recite prayers from the Koran. But then the school would have to show how to daven and how to take communion, and how to do a rain dance, too. But saying prayers is religion and it's well defined in case law by the USSC. That is why the 9th had to call it a "culture" in order to circumvent the precedent.
Its totally bizarre since one would think that this so-called "liberal court" would have decided the other way, against prayers. I guess they want to force the USSC to define religion?
