In many countries it is possible for parents to withdraw their children from parts or all of religious education courses. Here is an example letter broaching this sometimes sensitive subject with the school.
We understand that Islam is to be included in this year’s curriculum. Unfortunately we wish our child not to be included in the relevant lessons. We feel that if you present Mohammed as a benign lawgiver and prophet, as he is invariably presented, that would be dishonest. On the other hand if you present him honestly then it is likely to give any young child nightmares.
From Islam’s own scriptures we learn that Mohammed was indeed a religious leader but also a caravan raider, a ruthless warlord and a child-rapist who encouraged sex-slavery of non-Muslim women and employed torture and genocide in his drive toward power.
Allah hardly seems a benign deity either, repeatedly promising in the Koran to torture for eternity all those who do not believe in him. As far as we understand, that includes ourselves, our child and you too.
If you can disprove these claims then we would be grateful to be enlightened but otherwise we would only be happy for our child to learn about Islam at an age when they are old enough to fully comprehend the facts.
