No need to apologize. I wasn't offended. It's just that your comparison to rap music might have insinuated a point about racism.
I agree I'm close-minded on this, but I don't think it's a matter of subjective taste. The subjective question is about what counts as good poetry or good art in general. I'm asking about the difference between prose and poetry, which is a prior question of classification. Of course, the question of the difference between art and non-art is fraught, and that's because art is perhaps dead, as I've written about elsewhere (links below, if you're interested).
But the essential difference between prose and poetry strikes me as less complicated. Is the writer trying to be unusually creative in her choice of words? If she is, she's writing poetically, and this isn't the same as whether she's resorting to poetic trappings, to rhymes and rhythms (although such trappings and formalities can work well too).
