Racism, sexism, and religious intolerance are all seperate things but each may be a basis for discrimination. Both are learned from others (usually parents) at a young age. The tool is education of the young in a setting where races, sexes, and religions are mixed in a classroom where they learn to be friends from the beginning. There should be no tolerance for religious dogma or racism in education. Private schools based on either religious or cultural lines should be abolished. The children themselves will solve many of the worlds problems if their minds are not poisoned by adults, but after it happens the poison is almost impossible to remove.
