MoQ 5: "Took-me-out" Criticism

In the poetry workshop classes I've taken, there was a common expression used whenever a poem expressed its mechanics too fully, or any other vague offense it had committed.  The offended would claim that he or she had been taken out of the (reality? of the) poem.  No further explanation needed, no further help provided. 
Poetry is not creative non-fiction, it is free to expose how it works (in fact, this should be encouraged), poetry is allowed to implode on its own irony.  Poetry is not Show Choir.
It is rather jejune of anyone to think otherwise.
One moment of hypocrisy: I honestly believe that only left-aligned poetry is capable of having pleasing qualities.
