This quote is discussing the issue of racism, which is the belief that one race is superior to another. The speaker is asking a question about why they are black, and the answer they are given is that they were born in sin and shamed inequity. This suggests that the speaker is being taught they are not considered equally to other races, because race is linked to their sin and inequity. The speaker is also referring to a song they are taught to sing in church, which implies that their race should not be accepted and they should long to be whiter than snow, to signify greater purity. This serves to reinforce racist ideas that lighter complexions are superior to darker complexions.
