Faith schools remove the rights of children to choose their own religious, philosophical and ethical beliefs. They also sanction ethnic segregation and create tension and divisiveness within society. Schools should be places where children are given a free education, not centres for indoctrination. Creationism and other religious myths should not be taught as fact regardless of the funding status of a school. Abolishing faith schools will provide children with more freedom of choice and help to promote a fully multi-cultural, peaceful society.
