Man, "Theme for English B" sure talks a lot: about race, about America, about truth, and lots of big questions. Still, at its heart, it's about a 22-year-old man who is trying to find out exactly who he is. Of course, searching for his identity involves asking questions about the world around him, but when it comes down to it, he's examining the world around him by first asking himself how he fits into that super-sized Rubik's cube. At the same time, this poem links one man's identity to an entire country's identity. As this man is trying to find out who he is, America is full of racial tension, and hasn't really reached a stable identity itself. Much like the cube, it's a tricky puzzle to solve!
Identity's only skin deep. The speaker in this poem believes that race is the most important factor in determining his identity.
The map is where it's at. The places where the speaker lives are more important to his identity than race is.
