None, any or all of the above as THEY decide. For instance, let's say the school sets a threshold of at least ten kids all signing up for christian instruction, they might decide it should be general christian ideology, but what if they get 30 kids all interested in learning more about christian faith and 28 of them are Baptist, then they might decide to make the class specific to Baptist faith. The whole point is that:
- Religion is a legitimate branch of learning.
- That the school nor government have any say in picking or limiting the class.
I'm not saying that the school must have intensive study, but IF they have the facilities, means and interest, it SHOULD be an option open to consideration by them and for them, so I cannot answer for what they might find best suits them. Point is that if there is strong interest for this in the school district, then to limit or stop them in educating their children and using their facilities paid through their taxes as they see fit, /WOULD/ be a violation of their constitutional right to separation of church and state!
Again, I cannot say you are right or wrong. I can neither agree nor disagree. It might depend on the curriculum, where there is time or space, or pursued once a week after regular class. It is up to the SCHOOL, the students and parents who use that school to decide for themselves how best to use their facilities as any spiritual training would be under the student's and parent's direction and not the school's. Or maybe it wouldn't work there at all in their case--- the point is, it is up to THEM, not me.
