And can you prove any of that? What are the characteristics of that classic style? What are some other poems written in that style that have the same features as Gorman's?
The links below take you to some classic African American poems. I don't see any similarities between them and Gorman's. The ones below look like normal, real poems, filled with concrete images, specificity, and avoidance of abstractions, platitudes, and cliches.
The only trace of an African American style in Gorman's poem is her use of some cadence, which hints at jazz. She also uses some irregular and inexact rhymes which have the same effect. But these days those formalities can only adorn a poem; they can't substitute for poetic essence. If the writing itself isn't fine-grained and creative or original, the mere fact that there are some rhyming rhythms won't make the writing essentially poetic. And that's obviously so regardless of the author's skin colour.
Your accusation that my article is part of a denigration of non-white culture is laughable. I attack all aspects of white culture in my writings, from top to bottom, including the fake poetry on Instagram that's written mostly by pretty white people.
I'm afraid that the ability to string together words does make you a writer. What else could writing be? What you likely mean to say is that that ability doesn't make someone a professional writer. I never claimed to be one, so that would be neither here nor there.
My article seems to have triggered you, since you stooped to making personal attacks. Your style of overheated arguments by assertion belong on Twitter with the drooling mobs. Are you sure you're in the right place?
