Very good comment, @simao
The silly stereotyping of Rap music (as in the quote that you included) is a dead giveaway of the cultural myopia to which you refer.
There are countless examples of Rap that shatter such stereotypes, and I will offer one that does so on a variety of levels: Anthony Joseph.
Not only is the music that Joseph produces (at times in collaboration) often very different from stereotypical Rap, but he teaches creative writing at the University of London (as in England), has published at least four volumes of poetry (which clearly inform his music), and a novel.
Readers should have a listen to TIME, which he produced in collaboration with the excellent NY-based American bassist and singer Meshell Ndegeocello.
