I would say don't accomodate in this situation. The parent is off-base. The decision as to whether to take the child out of the school or not is up to the parent. If they send their child to a church or to a religious school, the child is more than likely going to hear some religious talk. If the parent doesn't want their children to hear religious talk, they shouldn't send them to a church or a religious school in the first place. End of story.

That's sort of like going to an ice cream parlor and bitching about the menu choices because they're lactose intolerant. Why did they come in in the first place?
