An Indonesian wife of a friend once told us that the difference between the different educational system can be indicated bt art class. In a western school children and given a piece of paper and crayons etc and asked to draw say sunset on the beach. Each child draws a different picture. In an Indo school like the one she went to, children are given a pre-drawn image and told to colour inside the lines.
So one could see the law change to be to stop radical (sic) free thinking. The Islamic argument may work but in some areas teachers are Christian.
