I think religion should be a compulsory subject at early age. That is not to say it is not studied like bible classes at a church. Let the church do it's job (faith) and the school its (education). But since religion plays such a big part in everyday life (hey its 50% of the chat forbidden topics here) then it makes sense that kids should know about it, especially in these troubled times where there is a lot of misunderstanding and animosity between islam and christianity.
I read the Quaran whilst in Saudi and discussed many of the more controversial areas with arabs. This knowledge has served me well in my dealings with muslims and opinions on the current problesm in the middle east.
