Poetry as sideways comment. All about misdirection. Describe one thing mean another. Just as speculative fiction, fantasy and science fiction comment on the here and now by being descriptions of an elsewhere, so poetry does the same.
Even so called “poetry without bells and whistles” takes you elsewhere. It is not just about a person drinking in a bar, sleeping with folk. It may describe a place you’ve often been to but give you a different slant on that place.
The “different slant” is the important bit. Having a different point of view means the writer takes you to another place.
For me all writing is speculative. It never describes what it seems to, and always comments on your life in the present.
