"There are those who get upset with me because I say that unless something rhymes and has rhythm, it’s not poetry. They mention all sorts of great names."

I think that explicitly denies that any free verse meets her definition of poetry. She clearly has no use for Eliot, whom she would also dismiss for writing non-poems that are much too long, like The Waste Land. Do you imagine that she would have anything positive to say about Ginsburg's Howl? By her definition, Tennyson's "Odysseus" would not qualify, since it does not rhyme, and she would throw out most of Angelou's poems for the same reason.

As for dissing poetry as a form or a profession, she says English majors aren't very bright, and that there is no money in poetry because prose does a much better job of expressing emotion. And her addendum makes it clear that she has nothing but contempt for any poet who takes exception to her unsupportable opinions, because they are obviously invested in believing there is value in writing she personally does not approve of.
