Here's a comment from the article page I found interesting and, from a foreigner's viewpoint, not just a little horrifying:

It's not just faith schools that are an issue. My child goes to a secular school where the new Head wants to have the local C of E minister in to preach to them every week. Her defence is that it is the statutory duty of the school to provide a daily act of collective worship. This is a quote from teachernet:
"The head teacher is responsible (under the School Standards and Framework Act 1998) for arranging the daily collective worship after consulting with the governing body. Daily collective worship must be wholly or mainly of a broadly Christian character. The precise nature will depend on the family background, ages and abilities of the pupils. However, if it is inappropriate for some or all of the pupils to take part in Christian collective worship, the head teacher may apply to the local Standing Advisory Council on Religious Education (SACRE) for a determination to have this requirement lifted."

That's right folks, It's the law that our children are indoctrinated unless we opt out. So much for a secular society.

Now if you want to start a campaign about religion in schools, surely getting this piece of nonsense off the statute books is the place to start. Make this your next campaign and I am in.
