i don't even know what that means. as if being black-latino (afro-latino) precludes someone from becoming a writer? i think veronica chambers, junot diaz, nicolas guillen, paulo lins, sofia quintero, and piri thomas (just to name a few black-latino writers) might say no, that heritage it is not a curse to writing.
Get over that stuff and write the best stuff you can
No worse than being a white European when it comes to reading.
