Pretty good. Let me add a few things. The coal, bein' black, is ripped up from the ground where it has been for a long, long, time, transported far, far away without its consent, segregated in coal bins (all the same color stuff in those coal bins!), and then it is used up to provide indirect labor for a mostly white American society. The ashes are discarded like they were never anything.
Sounds pretty racis' to me!
The company should have shown it is even-handed by mining some white coal.
