I imagine most everyone has read this, but I went back and reviewed Ira Sadoff's article on neo-formalism, available on line,
http://www.writing.upenn.edu/~afilreis/88/sadoff.html He attacks rhyme and meter as "dangerously nostalgic" and charges that poets who use rhyme trade complexity for ornamentation.
So he says things like "Poems that privilege sound and meter are conservative, then, not so much because they privilege tradition, but because they decontextualize poetry"; or "The neo-formalists' perhaps unconscious exaltation of the iamb veils their attempt to privilege prevailing white Anglo-Saxon rhythms and culture."
Read it yourelf if you haven't already. This illustrates the kind of knee-jerk reaction to rhyme that is a deep-structure in modern critical attitude.
