Nancy Gish: Williams did not like Eliot's and thought he had ruined poetry. But I see no reason to read this poem as about or referring to Eliot as it is the kind of thing Williams often wrote about.
Any "strong poet" (in Bloom's sense) is probably not a healthy "influence" on other poets - but no one is to be blamed if others choose to be corrupted by him.
Perhaps CR thinks all references to episcopal preachers have Eliot in mind. I wonder what he thinks of The Red Dean.
Williams is one of the poets I've always wished I had spent more time with.x
