Now that Brownlee says he shall speak no more, let me ask him a few questions.
The numerous sonic and other devices you mention are well known to any experienced poet, whether by name or not, and do not bear mention here except to say these are devices, manners of writing, like punctuation and capitalization the province of the writer's will, not a matter of strict form (or not). I notice two exceptions, isochrony and lineation, apparently inserted to confound and defeat the linguistic heathen. Lineation means line-drawing, which brings to mind that obscure and ill-defined thing known as a "line," thus "an aural and visual stretch of words." Isochrony refers to line-drawing to points in synchronous fashion, an interesting spelling bee word but of apparently little use in normal writing. If you would be so kind to do so, please explain their poetic use.
You also include, in your latest list of post-modern radicals, Emily Dickinson and Wallace Stevens. I am something of a Wallace Stevens fan, less so of Ms. Dickinson, but it would be of great interest to know how either of them got on your list of free-verse sonnets. So please provide citations.
Also, for the umpteenth time you say that no one on this site knows how to read or understand free verse, implying that we don't know how to write it either. This brings up an interesting question, since all the people who frequent these boards are either well experienced poets or younger ones giving it a try. The ones who have been writing for years or decades could be presumed to know how to read a poem. Honestly, this is just a matter of common sense. We often agree or disagree on these boards, but that is far from not knowing what we are talking about. What makes you think that, as a group, the case is contrary? I mean, rather than just using it as an attribution like the the rosy colored fingers of dawn, could you be more precise in why you think, seemingly solely because we disagree with you on points, this group is a crowd of ignoramuses? Not in so many words, of course. You don't want to hurt our feelings.
Last, to be hoisted on one's own petard is about as elegant a way to suffer self-inflicted indignity as exists in English. Surely offense is not an appropriate feeling to have in that instance. Chagrin might be more to it.
