Tell her to take the child to another school - end of story.

She knew it was a religous school, she was not forced to send the child there, or maybe she knew it was a christian oriented school and did it anyway, knowing that she would have something to complain about in a short while. A little bit like fighting from the inside.

It is strange though that many people who do believe in a God or some higher diety and who do not want religion as any part of their or their childrens' lives are the first ones to scream " how could God let that happen, when disaster strikes ".

Just because religion is discussed at school does not mean it is being forced down anyone's throat, any more than geography, physics or any other subject. If this lady came and demended that her child be excused from science, algebra or whatever because those subjects were not going to be part of his life, what would the answer be .?.

Tell her to change schools and go on about your business.
