Contrast and metaphors are two of the techniques that are constantly used throughout Oodgeroo Noonuccal's poem 'Racism' to effectively portray the conflict between those who are being discriminated and oppressed (namely blacks) and those who are racist (whites). In this poem, Noonuccal is creating a distinction between blacks and whites which can be seen in the phrase 'white-black hatred sustains itself' which implies that all blacks and all whites are negatively inclined towards each other, which, in her opinion, is not far from the truth. This poem also uses metaphors but unlike other poems, this poem does not use metaphors to show the black people and white people, hence the words 'white-black'. In the very first line of the very first stanza Noonuccal writes that 'black, frustrated minds' are 'stalking the corridors of life'. The unseen metaphor in these phrases is that black people, confined as they are, have to walk through 'corridors of life' meaning that they are being oppressed, being pushed into a single way of life or frame of mind. This can also be seen in the phrase 'Black, frustrated minds/Scream for release/From Christian racist moulds.' which is relating to the fact that black people, having been oppressed their whole lives, are 'Screaming for release' from their 'Christian racist moulds'. This means that white people have, as said before, been shaping or moulding the way that black people think and live their lives. Amongst black people, this would create a long-lived frustration and even annoyance towards white people which Noonuccal outlines with the phrase 'Black can be racist too/A violent struggle could erupt' which would see the tables turned. To conclude, contrast and metaphors are both commonly used throughout this poem to show the conflict between black people and white people, or the oppressed and the oppressors.
