'Half Caste' - Making Racism Ridiculous!

'Half Caste' is an anti-racist poem. A fun poem. A carnival poem. A poem of contradictions. It is, above all, a positive poem. A poem that tells us how good things are if we mix it up - if we take things and make them interesting by mixing things together. John Agard is trying to show us that the word 'Half Caste' is silly and meaningless, by using humour.
