 Studying John A. God's poem, Half-Cost, let's discuss how you can analyse this poem. He repeatedly asks, explain yourself what you mean and this is an imperative sentence. He is demanding from the racist person what exactly they mean by this racist term. He uses the words light, shadow, sky and weather, which belong to the semantic field of nature to ask if things mix naturally in nature. Is this unnatural? In similar ways, we are triggered to wonder if the mixing of races is also unnatural if this already happens in nature. Although the tone is overall one of disgust, he does have some humorous reference. He says, England weather nearly always half-cast. Here he's talking about how the English weather is always grey, a mix of light and darkness. Bear in mind, he uses words like them till D. This means he writes phonetically. He writes exactly as the words are pronounced using what is called patois dialect. The speaker shows his anger by saying arras, which is an expletive. It's a swear word in patois.
